After contrasting Noah’s righteous, blameless life of faith and daily walk with God against a world “corrupt before God” and “filled with violence,” this lesson next details God’s command to construct a three-story, pitch-sealed ark. Noah and his family entered by faith, and God supernaturally gathered two of every land-dependent animal “kind” plus extras of the clean kinds, then sealed them all inside just before the fountains of the great deep burst and the windows of heaven opened, drowning every living thing outside while the ark safely floated for 150 days. The ark is presented as a picture of our salvation—planned from eternity past, entered by faith alone for deliverance from judgment, sealed by God for total security, and entered through a single door (Christ).
