In the closing verses of Psalm 139, David zealously prayed for the destruction of the wicked—then submitted himself to divine scrutiny as well. Like David, Christians should hate evil and long for its eradication, explains Alistair Begg. 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, trust Jesus, and be saved by grace from God’s wrath.
