In the closing verses of Psalm 139, David zealously prayed for the destruction of the wicked and then submitted himself to divine scrutiny as well. Like David, Christians should hate evil and long for its eradication. Vengeance, however, isn’t our responsibility. God alone judges righteously. Only when we understand His holiness and purity will we realize how lost and sinful we truly are; only then will we place our trust in Jesus, and be saved by grace from God’s wrath.
