If only you, God, would slay the wicked! Away from me, you who are bloodthirsty! They speak of you with evil intent; your adversaries misuse your name. Do I not hate those who hate you, Lord, and abhor those who are in rebellion against you? I have nothing but hatred for them; I count them my enemies. Psalm 139:19-22 NIV
David suddenly turned his attention from the Lords wonderful work in our lives to the wickedness in the world. He was keenly aware of evil people whose activities opposed Gods purposes. Indeed, wicked men had tried repeatedly to thwart God’s plan for his own life. David prayed passionately for God to judge the wicked, and he ordered these violent men to stay away from him.
David called on God to remove the wicked from the world so that His righteousness and love could flow freely. He prayed specifically against the bloodthirsty men who opposed God’s people and opposed the purpose and plans God had for them. They hated God’s people so viciously because they themselves hated God.
David declared his unwavering loyalty to God, stating plainly that he hated those who hated the Lord. Besides that, he grieved or was disgusted by their opposition to God. David’s hatred of the wicked was motivated by his zeal for the Lord. He despised the wicked so strongly because he loved the Lord so passionately. He viewed God’s enemies as his own enemies.
When Christ came, He gave us, His followers, a new command to follow with regard to our enemies: we are to love and pray for our enemies. Why? Because God desires for all people to repent and be saved (2 Peter 3:9). At the same time, we are commanded to stand against all evil and wickedness. While we are on a mission to win every lost person to Christ, we are also warned about friendship with the world. Ultimately, we should remember that our enemies are not flesh and blood but are instead powers and rulers of darkness.
As followers of Christ, we need to constantly seek the balance that Jesus spoke about: to be in the world, but not of the world. That is, we are to be a part of the world so we can reach people for Christ and uphold righteousness, but we must not let the evil of the world pull us away from obedience to God.
This balance is also stated in the saying, “Hate the sin but love the sinner.” We are to stand strongly against everything that is opposed to God and His truth. But while doing so, we are to show the love of Christ to all who are a part of those things. We are to do everything possible to reach them with the life-saving gospel of Jesus Christ.
The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance. 2 Peter 3:9 NIV
