“But of that day and hour [the rapture] no one knows, no, not even the angels of heaven, but My Father only. But as the days of Noah were, so also will the coming of the Son of Man be. For as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and did not know until the flood came and took them all away, so also will the coming of the Son of Man be.” Matthew 24:36-39.
Sometime after the creation of Adam and Eve on the sixth day of creation, see Genesis 1:26-31, they rebelled against God by eating the fruit of the tree of the knowledge of good and evil.
By doing so they brought sin into the world and upon all of humanity. The details of this are in Genesis 3:1-24.
“This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the futility of their mind, having their understanding darkened, being alienated from the life of God, because of the ignorance that is in them, because of the hardening of their heart; who, being past feeling, have given themselves over to licentiousness, to work all uncleanness with greediness.” Ephesians 4:17-19.
“For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ: whose end is destruction, whose god is their belly, and whose glory is in their shame – who set their mind on earthly things. For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly body that it may be conformed to His glorious body, according to the working by which He is able even to subdue all things to Himself.” Philippians 3:18-21.
