Among many calendar reform proposals that eliminate the constant seven-day week in exchange for simplified calculation of calendrical data like weekday names for given dates, some retain Sabbatical influences. The Hermetic Lunar Week Calendar uses moon phases, resulting in weeks of six to nine days. The International Fixed Calendar and World Calendar both consist of 364-day years containing exactly 52 weeks (each starting on a day designated as Sunday), with an additional one or two intercalary "blank" days not designated as part of any week (Year Day and Leap Day in the International Fixed Calendar; Worldsday and Leapyear Day in the World Calendar). Reform supporters sought to accommodate Sabbatical observance by retaining the modified week and designating the intercalary days as additional Sabbaths or holidays; however, religious leaders held that such days disrupt the traditional seven-day weekly cycle. This unresolved issue contributed to the cessation of reform activities in the 1930s (International Fixed Calendar) and again in 1955 (World Calendar), though supporters of both proposals remain.

In June 2001, Tropical Storm Allison dumped up to 40 inches (1,000 mm) of rain on parts of Houston, causing what was then the worst flooding in the city's history. The storm cost billions of dollars in damage and killed 20 people in Texas.[38] By December of the same year, Houston-based energy company Enron collapsed into the largest U.S. bankruptcy (at that time), a result of being investigated for off-the-books partnerships which were allegedly used to hide debt and inflate profits. The company lost no less than $70 billion.[39]
In modern times Orthodox Jews strive to observe the Sabbath with full solemnity. Conservative Jews vary in their practice, some seeking certain modifications to permit, for instance, travel on the Sabbath. Reform Jews, in some cases, hold synagogue services on Sunday. Among post-Reformation Christians, a few groups, such as the Seventh-day Adventists, observe Saturday as their day of rest and worship.

By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton.[20] Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Magruder, who used the city as an organization point for the Battle of Galveston.[22] After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between Downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.

During its recent history, Houston has flooded several times from heavy rainfall, which has been becoming increasingly common.[43] This has been exacerbated by a lack of zoning laws, which allowed unregulated building of residential homes and other structures in flood-prone areas.[44] During the floods in 2015 and 2016, each of which dropped at least a foot of rain,[45] parts of the city were covered in several inches of water.[46] Even worse flooding happened in late August 2017, when Hurricane Harvey stalled over southeastern Texas, much like Tropical Storm Allison did sixteen years earlier, causing severe flooding in the Houston area, with some areas receiving over 50 inches (1,300 mm) of rain.[47] The rainfall exceeded 50 inches in several areas locally, breaking the national record for rainfall. The damage for the Houston area is estimated at up to $125 billion U.S. dollars,[48] and it is considered to be one of the worst natural disasters in the history of the United States,[49] with the death toll exceeding 70 people. On January 31, 2018, the Houston City Council agreed to forgive large water bills thousands of households faced in the aftermath of Hurricane Harvey, as Houston Public Works found 6,362 homeowners' water utility bills had at least doubled.[50][51]
Since Hippolytus of Rome in the early third century, Christians have often considered that some thousand-year Sabbath, expected to begin six thousand years after Creation, might be identical with the millennium described in the Book of Revelation. This view was also popular among 19th- and 20th-century dispensational premillennialists. The term "Sabbatism" or "Sabbatizing" (Greek Sabbatismos), which generically means any literal or spiritual Sabbath-keeping, has also been taken in Hebrews 4:9 to have special reference to this definition.
George Bush Intercontinental Airport (IAH), located 23 miles (37 km) north of Downtown Houston between Interstates 45 and 69, is the eighth busiest commercial airport in the United States (by total passengers and aircraft movements) and forty-third busiest globally.[286][287] The five-terminal, five-runway, 11,000-acre (4,500-hectare) airport served 40 million passengers in 2016, including 10 million international travelers.[286] In 2006, the United States Department of Transportation named IAH the fastest-growing of the top ten airports in the United States.[288] The Houston Air Route Traffic Control Center is located at Bush Intercontinental.
The Seventh-day Adventist Church operates youth camps all over North America and many other parts of the world. Each camp varies in the activities they offer but most have archery, swimming, horses, arts and crafts, nature, high ropes challenge course, and many other common camp activities. In addition to regular camps some have specialty camps, or RAD camps, which vary in their activities such as a week of nature nuggets, surfing, waterskiing/wakeboarding, rock climbing, golf, skateboarding, whitewater rafting, mountain biking, cycling, or basketball.

"In the beginning was the Word, .... and the Word was God. .... All things were made through him; and without him was not anything made that hath been made." But this same Word which was with God, and was God, "became flesh, and dwelt among us" (John 1:1,3,14). This is the eternal Son, "in whom we have our redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace" (Ephesians 1:7). To the Christian the Sabbath, which was the sign and memorial of that divine power which wrought through the eternal Word in the creation of the heaven and the earth, becomes the sign of the same power working through the same eternal Son to accomplish the new creation, and is thus the sign of both the divinity and the deity of Christ.
And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen. ~ Matthew 28:18-20
During the summer, temperatures in Houston commonly reach over 90 °F (32 °C). The city reaches or surpasses this temperature on an average of 106.5 days per year, including a majority of days from June to September; additionally, an average of 4.6 days per year reach or exceed 100 °F (38 °C).[73] Houston's characteristic subtropical humidity often results in a higher apparent temperature, and summer mornings average over 90% relative humidity.[74] Air conditioning is ubiquitous in Houston; in 1981, annual spending on electricity for interior cooling exceeded $600 million (equivalent to $1.65 billion in 2018), and by the late 1990s, approximately 90% of Houston homes featured air conditioning systems.[75][76] The record highest temperature recorded in Houston is 109 °F (43 °C) at Bush Intercontinental Airport, during September 4, 2000, and again on August 27, 2011.[73]

Houston is home to the largest Muslim population in Texas and the Southern United States as of 2012.[138] It is estimated that Muslims make up 1.2% of Houston's population.[138] As of 2016 Muslims in the Houston area included South Asians, Middle Easterners, Africans, Turks, and Indonesians. In 2000 there were over 41 mosques and storefront religious centers, with the largest being the Al-Noor Mosque (Mosque of Light) of the Islamic Society of Greater Houston.[139]

The sketch of creation in Genesis 1:1-2:3 closes with an impressive account of the hallowing of the 7th day, because on it God rested from all the work which He had made creatively. The word "Sabbath" does not occur in the story; but it is recognized by critics of every school that the author (P) means to describe the Sabbath as primeval. In Exodus 20:8-11 (ascribed to JE) the reason assigned for keeping the 7th day as a holy Sabbath is the fact that Yahweh rested after the six days of creative activity. Exodus 31:17 employs a bold figure, and describes Yahweh as refreshing Himself ("catching His breath") after six days of work. The statement that God set apart the 7th day for holy purposes in honor of His own rest after six days of creative activity is boldly challenged by many modern scholars as merely the pious figment of a priestly imagination of the exile. There are so few hints of a weekly Sabbath before Moses, who is comparatively a modern character, that argumentation is almost excluded, and each student will approach the question with the bias of his whole intellectual and spiritual history. There is no distinct mention of the Sabbath in Gen, though a 7-day period is referred to several times (Genesis 7:4,10; 8:10,12; 29:27). The first express mention of the Sabbath is found in Exodus 16:21-30, in connection with the giving of the manna. Yahweh taught the people in the wilderness to observe the 7th day as a Sabbath of rest by sending no manna on that day, a double supply being given on the 6th day of the week. Here we have to do with a weekly Sabbath as a day of rest from ordinary secular labor. A little later the Ten Words (Commands) were spoken by Yahweh from Sinai in the hearing of all the people, and were afterward written on the two tables of stone (Exodus 20:1-17; 34:1-5,27). The Fourth Commandment enjoins upon Israel the observance of the 7th day of the week as a holy day on which no work shall be done by man or beast. Children and servants are to desist from all work, and even the stranger within the gates is required to keep the day holy. The reason assigned is that Yahweh rested on the 7th day and blessed it and hallowed it. There is no hint that the restrictions were meant to guard against the wrath of a jealous and angry deity. The Sabbath was meant to be a blessing to man and not a burden. After the sin in connection with the golden call Yahweh rehearses the chief duties required of Israel, and again announces the law of the Sabbath (Exodus 34:21, ascribed to J). In the Levitical legislation there is frequent mention of the Sabbath (Exodus 31:13-16; 35:2; Leviticus 19:3,10; 23:3,18). A willful Sabbath-breaker was put to death (Numbers 15:32-36). In the Deuteronomic legislation there is equal recognition of the importance and value of the Sabbath (Deuteronomy 5:12-15). Here the reason assigned for the observance of the Sabbath philanthropic and humanitarian:
This summary of history must necessarily be brief, and it will be impossible, for lack of space, to quote authorities. From the testimony of Josephus it is clear that the Jews, as a nation, continued to observe the seventh-day Sabbath until their overthrow, when Jerusalem was captured by Titus, 70 AD. As colonies, and individuals, scattered over the face of the earth, the Jews have preserved a knowledge of the original Sabbath, and the definite day, until the present time. They constitute a living testimony for the benefit of all who desire to know the truth of this matter.

Most Adventists believe some variant of annihilationism, which says that after final judgment, all unbelievers will be destroyed rather than suffering in hell. In this belief, the Old Testament and New Testament say that the final end for nonbelievers is total extinction. For example, in Romans, Paul describes hell as a final punishment, where the wicked die, perish or are destroyed.
There were 943,183 housing units in 2017 and 838,950 households.[119] 43.3% of Houstonians owned housing units with an average of 2.66 persons per household. The median monthly owner costs with a mortgage were $1,533, and $511 without a mortgage. Houston's median gross rent from 2013-2017 was $940.[119] The median household income in 2017 was $49,399 and 21.2% of Houstonians lived below the poverty line.
Shmita (Hebrew: שמטה‎, Strong's 8059 as shemittah, literally "release"), also called sabbatical year, is the seventh (שביעי, Strong's 7637 as shebiy'iy) year of the seven-year agricultural cycle mandated by Torah for the Land of Israel, relatively little observed in Biblical tradition, but still observed in contemporary Judaism. During Shmita, the land is left to lie fallow and all agricultural activity, including plowing, planting, pruning and harvesting, is forbidden by Torah and Jewish law. By tradition, other cultivation techniques (such as watering, fertilizing, weeding, spraying, trimming and mowing) may be performed as preventative measures only, not to improve the growth of trees or plants; additionally, whatever fruits grow of their own accord during that year are deemed hefker (ownerless), not for the landowner but for the poor, the stranger, and the beasts of the field; these fruits may be picked by anyone. A variety of laws also apply to the sale, consumption and disposal of Shmita produce. When the year ended, all debts, except those of foreigners, were to be remitted (Deuteronomy 15:1–11); in similar fashion, Torah requires a slave who had worked for six years to go free in the seventh year. Leviticus 25 promises bountiful harvests to those who observe Shmita, and describes its observance as a test of religious faith. The term Shmita is translated "release" five times in the Book of Deuteronomy (from the root שמט, shamat, "desist, remit", 8058).

By synecdoche (naming the whole for a part), in Jewish sources by the time of the Septuagint, the term "Sabbath" (Greek Sabbaton, Strong's 4521) also came to mean an entire "se'nnight" or seven-day week, the interval between two weekly Sabbaths. Jesus's parable of the Pharisee and the Publican (Luke 18:9–14) describes the Pharisee as fasting "twice a week" (Greek dis tou sabbatou, literally, "Twice of the Sabbath").
A concrete illustration of this gospel meaning of the Sabbath is found in the deliverance of Israel from Egypt. The same creative power which wrought in the beginning was exercised in the signs and miracles which preceded their deliverance, and in those miracles, such as the opening of the Red Sea, the giving of the manna, and the water from the rock, which attended the journeyings of the Israelites. In consequence of these manifestations of creative power in their behalf, the children of Israel were instructed to remember in their observance of the Sabbath that they were bondsmen in the land of Egypt. Israel's deliverance from Egypt is the type of every man's deliverance from sin; and the instruction to Israel concerning the Sabbath shows its true significance in the gospel of salvation from sin, and the new creation in the image of God.
Apart from His claim to be the Messiah, there is no subject on which our Lord came into such sharp conflict with the religious leaders of the Jews as in the matter of Sabbath observance. He set Himself squarely against the current rabbinic restrictions as contrary to the spirit of the original law of the Sabbath. The rabbis seemed to think that the Sabbath was an end in itself, an institution to which the pious Israelite must subject all his personal interests; in other words, that man was made for the Sabbath:
Three community college districts have campuses in and around Houston. The Houston Community College System (HCC) serves most of Houston proper; its main campus and headquarters are located in Midtown. Suburban northern and western parts of the metropolitan area are served by various campuses of the Lone Star College System, while the southeastern portion of Houston is served by San Jacinto College, and a northeastern portion is served by Lee College.[249] The Houston Community College and Lone Star College systems are among the 10 largest institutions of higher learning in the United States.

The Biblical Research Institute is the official theological research center of the church. The church has two professional organizations for Adventist theologians who are affiliated with the denomination. The Adventist Society for Religious Studies (ASRS) was formed to foster a community among Adventist theologians who attend the Society of Biblical Literature (SBL) and the American Academy of Religion. In 2006, ASRS voted to continue their meetings in the future in conjunction with SBL. During the 1980s, the Adventist Theological Society was formed to provide a forum for more conservative theologians to meet and is held in conjunction with the Evangelical Theological Society.[39]
