The destruction of the world before the flood is a picture of the judgment that shall take place in the last days. All those who set their hearts against the Lord will perish. Although this is a just end that comes upon a rebellious people, it is also a sad picture. Many generations had passed sins Adam transgressed. In all those years God was “striving with man.” (Gen. 6.3) However, as God was calling sinners to Himself, they rebelled more and more. The same is true today. Jesus Christ commanded that the gospel be preached to every creature.
