How does the story of Noah relate to the second coming of Christ?

Jesus referenced the days of Noah to illustrate the unprepared state of mankind before His second coming. Just as the world was ignorant and dismissive of coming judgment during Noah's time, so will many people be unaware and unprepared when Christ returns. The flood signifies divine judgment, while the ark represents salvation. The call to be ready for the return of Christ echoes the urgency present in Noah's preaching, urging believers to heed God's word and live in anticipation of Christ’s return, prepared and righteous in Him.
