How long did God leave the ark door open after Noah finished the ark?
After the ark was finished, God left the gangplank down and the door open for seven days. This period allowed those consumed by normal activities and corruption to enter and escape the coming flood and God's wrath, but none did except Noah's family.
Les explains that even after the ark was finished, God did not immediately close it. He left the gangplank down and the door open for seven days. During that time, people were eating, drinking, marrying, giving in marriage, working, and building, while the earth was also corrupt and filled with violence. They could have stepped in, escaped the flood, escaped God's wrath, and enjoyed salvation, but only Noah's family entered. None others took the opportunity, which pictures the days before the coming of the Son of Man.
