What does Psalm 36:12 mean?

In recent verses, David has been praying for God's defeat of evil and wicked enemies (Psalm 36:10–11). Here, he expresses supreme confidence in the Lord's eventual victory. This statement depicts those same enemies as if they are already beaten. He foresees a time when they lie fallen and unable to rise again.

At times, we fear a defeated enemy may regroup and attack once again. In the end times, God will accomplish an absolute and irreversible victory. After the rapture, when God removes Christians from the earth, the seven-year tribulation period takes place. Many Jews will come to know the Lord as their Messiah, but they will face intense persecution from the man of sin and his followers. The Devil will use the wicked to pursue and persecute the saved Jews (Revelation 12). However, at the end of the tribulation, Jesus will return to earth. He will deliver His persecuted tribulation saints. He will thoroughly defeat and destroy the wicked.

Revelation 19:11–21 unveils the picture of this decisive victory, and Revelation 20:7–15 relates the final punishment of everyone whose name is not written in the Lamb's book of life. Today, at times it seems that the wicked are winning the war against the righteous, but ultimately the tables will turn, and both sin and death will be "thrust down," never to rise again (2 Peter 3:8–13).
