Genesis 7:6-16 reveals God's sovereign plan during the flood, preserving His covenant promise and creation through Noah's family. This wasn't merely judgment but restoration, demonstrating God's providence and faithfulness to His people. The passage highlights three crucial lessons: our eternal security in God's hands, His abundant grace in delaying judgment, and the reality that His grace has a deadline. Just as God shut Noah in the ark, securing his salvation, believers today are secure in Christ. However, like in Noah's day, a time is coming when the door of salvation will close, making today the day to respond to God's offer of grace.
