A system of toll roads, operated by the Harris County Toll Road Authority (HCTRA) and Fort Bend County Toll Road Authority (FBCTRA), provides additional options for regional commuters. The Sam Houston Tollway, which encompasses the mainlanes of Beltway 8 (as opposed to the frontage roads, which are untolled), is the longest tollway in the system, covering the entirety of the Beltway with the exception of a free section between Interstate 45 and Interstate 69 near George Bush Intercontinental Airport. The region is serviced by four spoke tollways: a set of managed lanes on the Katy Freeway; the Hardy Toll Road, which parallels Interstate 45 north of Downtown up to Spring; the Westpark Tollway, which services Houston's western suburbs out to Fulshear; and Fort Bend Parkway, which connects to Sienna Plantation. Westpark Tollway and Fort Bend Parkway are operated conjunctly with the Fort Bend County Toll Road Authority.
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]
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]
Houston generally receives ample rainfall, averaging about 49.8 in (1,260 mm) annually based on records between 1981 and 2010. Many parts of the city have a high risk of localized flooding due to flat topography,[81] ubiquitous low-permeability clay-silt prairie soils,[82] and inadequate infrastructure.[81] During the mid-2010s, Greater Houston experienced consecutive major flood events in 2015 ("Memorial Day"),[83] 2016 ("Tax Day"),[84] and 2017 (Hurricane Harvey).[85] Overall, there have been more casualties and property loss from floods in Houston than in any other locality in the United States.[86] The majority of rainfall occurs between April and October (the wet season of Southeast Texas), when the moisture from the Gulf of Mexico evaporates extensively over the city.[86][83]
Critics such as evangelical Anthony Hoekema (who felt that Adventists were more in agreement with Arminianism) argue that some Adventist doctrines are heterodox. Several teachings which have come under scrutiny are the annihilationist view of hell, the investigative judgment (and a related view of the atonement), and the Sabbath; in addition, Hoekema also claims that Adventist doctrine suffers from legalism.[104]
This belief comes from Ecclesiastes 9, which says, “For the living know that they will die.” Another verse often pointed to for this belief is 1 Thessalonians 4:13-18, which says, “For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him. According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep. For the Lord, himself will come down from heaven … After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air.”
Puritan Sabbatarianism or Reformed Sabbatarianism is strict observance of Sabbath in Christianity that is typically characterized by its avoidance of recreational activities. "Puritan Sabbath", expressed in the Westminster Confession of Faith, is often contrasted with "Continental Sabbath": the latter follows the Continental Reformed confessions such as the Heidelberg Catechism, which emphasize rest and worship on Lord's Day, but do not forbid recreational activities.
The Houston Office of Protocol and International Affairs is the city's liaison to Houston's sister cities and to the national governing organization, Sister Cities International. Through their official city-to-city relationships, these volunteer associations promote people-to-people diplomacy and encourage citizens to develop mutual trust and understanding through commercial, cultural, educational, and humanitarian exchanges.[295][296]
Murders fell by 37 percent from January to June 2011, compared with the same period in 2010. Houston's total crime rate including violent and nonviolent crimes decreased by 11 percent.[230] The FBI's Uniform Crime Report (UCR) indicates a downward trend of violent crime in Houston over the ten- and twenty-year periods ending in 2016, which is consistent with national trends. This trend toward lower rates of violent crime in Houston includes the murder rate, though it had seen a four-year uptick that lasted through 2015. Houston's violent crime rate was 8.6% percent higher in 2016 from the previous year. However, from 2006 to 2016, violent crime was still down 12 percent in Houston.[231]
Hiram Edson and other Millerites came to believe that Miller's calculations were correct, but that his interpretation of Daniel 8:14 was flawed as he assumed Christ would come to cleanse the world. These Adventists came to the conviction that Daniel 8:14 foretold Christ's entrance into the Most Holy Place of the heavenly sanctuary rather than his Second Coming. Over the next few decades this understanding of a sanctuary in heaven developed into the doctrine of the investigative judgment, an eschatological process that commenced in 1844, in which every person would be judged to verify their eligibility for salvation and God's justice will be confirmed before the universe. This group of Adventists continued to believe that Christ's Second Coming would continue to be imminent, however they resisted setting further dates for the event, citing Revelation 10:6, "that there should be time no longer."[14]
