How do we know that God's judgment will come?

The certainty of God's judgment is underscored in Biblical narratives such as the account of Noah in Genesis 6, where the Lord decided to judge the wickedness of mankind. This historical event serves as a foreshadowing of the final judgment that will take place at the return of Christ, as reiterated in Matthew 24:37-39, where Jesus draws parallels between the judgment of the flood and His coming. By recognizing these Biblical assurances, believers can find hope and urgency in proclaiming the Gospel, knowing that God is just and His word will not return void.
