The major weekly worship service occurs on Saturday, typically commencing with Sabbath School which is a structured time of small-group bible study at church. Adventists make use of an officially produced "Sabbath School Lesson", which deals with a particular biblical text or doctrine every quarter.[41] Special meetings are provided for children and youth in different age groups during this time (analogous to Sunday school in other churches).

The Houston–The Woodlands–Sugar Land MSA's gross domestic product (GDP) in 2016 was $478 billion, making it the sixth-largest of any metropolitan area in the United States and larger than Iran's, Colombia's, or the United Arab Emirates' GDP.[150] Only 27 countries other than the United States have a gross domestic product exceeding Houston's regional gross area product (GAP).[151] In 2010, mining (which consists almost entirely of exploration and production of oil and gas in Houston) accounted for 26.3% of Houston's GAP up sharply in response to high energy prices and a decreased worldwide surplus of oil production capacity, followed by engineering services, health services, and manufacturing.[152]

The weekend is that period of the week set aside by custom or law for rest from labor. In many countries it is Saturday and Sunday and often includes Friday night. This five-day workweek arose in America when labor unions attempted to accommodate Jewish Sabbath, beginning at a New England cotton mill and also instituted by Henry Ford in 1926; it became standard in America by about 1940 and spread among English-speaking and European countries to become the international workweek. China adopted it in 1995 and Hong Kong by 2006. India and some other countries follow both the international workweek and a more traditional Saturday half-workday and Sunday weekend. While Indonesia and Lebanon have the international workweek, most Muslim countries count Friday as the weekend, alone or with Thursday (all or half) or Saturday. Some universities permit a three-day weekend from Friday to Sunday. The weekend in Israel, Nepal, and parts of Malaysia, is Friday (all or half) and Saturday. Only the one-day customary or legal weekends are usually called "Sabbath".
Her most known work was called “Steps to Christ,” where she answered questions on how to deal with doubt and also understanding the difference between grace and law. It’s been hailed as giving a practical approach to Christianity. For example, she writes, “Prayer is the opening of the heart to God as to a friend. Not that it is necessary in order to make known to God what we are, but in order to enable us to receive Him.” 
The meaning of the Sabbath institution comes to light against the background of several key facts. First, Exodus 20:8-11 makes a clear connection between the Sabbath day and the seventh day on which God the Creator rested. Sabbath observance therefore involves the affirmation that God is Creator and Sustainer of the world. To "remember the Sabbath" meant that the Jew identified the seven-day-a-week rhythm of life as belonging to the Creator. This connection is particularly important in light of the Jewish doctrine that human beings are co-partners with God. They receive the world in an unfinished state so that they may share with God the purposes he seeks by continuing to fashion and subdue the creation. If the Creator stopped his creative activity on the seventh day, then those who share in his creative work must do the same. Sabbath contravenes any pride that may accompany human mastery and manipulation of God's creation. In ceasing from labor one is reminded of one's true status as a dependent being, of the God who cares for and sustains all his creatures, and of the world as a reality belonging ultimately to God.
When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war.[28] Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators.[29] The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of nondiscrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years.[30]

Houston has the largest number of bike commuters in Texas with over 160 miles of dedicated bikeways.[278] The city is currently in the process of expanding its on and off street bikeway network.[when?][279] In 2015, Downtown Houston added a cycle track on Lamar Street, running from Sam Houston Park to Discovery Green.[280] In August 2017, Houston City Council approved spending for construction of 13 additional miles of bike trails.[281]

Comprising a total area of 637.4 square miles (1,651 km2),[8] Houston is the eighth most expansive city in the United States (including consolidated city-counties). It is the largest city in the United States by total area, whose government is not consolidated with that of a county, parish or borough. Though primarily in Harris County, small portions of the city extend into Fort Bend and Montgomery counties, bordering other principal communities of Greater Houston such as Sugar Land and The Woodlands.

In the prophets, observance of the Sabbath becomes the touchstone for Israel's obedience to its covenant with God. The future of Jerusalem depends on faithful Sabbath keeping ( Jer 17:24-27 ). One's personal well-being is also at stake ( Isa 56:2-7 ). Those who honor the day will find joy, riding on the heights of the earth and being fed with the heritage of Jacob ( Isa 58:14 ). As God once desired to destroy his people in the desert because of their Sabbath desecration ( Eze 20:12-14 ), so he now counts this among Israel's present moral failures ( Eze 22:8 ) for which there will be purging and dispersion. Amos issues a stern warning to those merchants who endure the Sabbath, anxious only to get on with the selling of grain ( 8:5 ).
For about 20 years, the Adventist movement consisted of a small, loosely knit group of people who came from many churches and whose primary means of connection and interaction was through James White's periodical The Advent Review and Sabbath Herald. They embraced the doctrines of the Sabbath, the heavenly sanctuary interpretation of Daniel 8:14, conditional immortality, and the expectation of Christ's premillennial return. Among its most prominent figures were Joseph Bates, James White, and Ellen G. White. Ellen White came to occupy a particularly central role; her many visions and spiritual leadership convinced her fellow Adventists that she possessed the gift of prophecy.[citation needed]
_{Many annual events celebrate the diverse cultures of Houston. The largest and longest-running is the annual Houston Livestock Show and Rodeo, held over 20 days from early to late March, and is the largest annual livestock show and rodeo in the world.[171] Another large celebration is the annual night-time Houston Gay Pride Parade, held at the end of June.[172] Other notable annual events include the Houston Greek Festival,[173] Art Car Parade, the Houston Auto Show, the Houston International Festival,[174] and the Bayou City Art Festival, which is considered to be one of the top five art festivals in the United States.[175][176]}
We tend to think of sabbatical in academic terms, as a school year free from teaching duties that can be devoted to research, travel, and writing. Traditionally, this occurs every seventh year. Because of this scholarly context, we may easily miss what is hiding in plain sight: that sabbatical is related to Sabbath, which refers to the Biblical day of rest, or the seventh day. We trace the origins of both sabbatical and Sabbath to the Greek word sabbaton. Sabbaton itself traces to the Hebrew word shabbāth, meaning “rest.”
The Seventh-day Adventist Church[a] is a Protestant Christian denomination[3] which is distinguished by its observance of Saturday,[4] the seventh day of the week in Christian and Jewish calendars, as the Sabbath, and its emphasis on the imminent Second Coming (advent) of Jesus Christ. The denomination grew out of the Millerite movement in the United States during the mid-19th century and it was formally established in 1863.[5] Among its founders was Ellen G. White, whose extensive writings are still held in high regard by the church.[6]
