He who Avenges Blood

This is a revelation of God's character that we don't often mention, but the psalmists (David here) are not so reticent to point it out. "When he maketh inquisition for blood, he remembereth them: He forgetteth not the cry of the humble" (Ps. 9.12, KJV). Vengeance for innocent blood is God's responsibility, and here we are promised that he will carry out his responsibilities. This is why as Christians we do not seek vengeance. Indeed we are called to love our enemies. God, who is the perfect judge, will carry out vengeance for innocent blood.

Here we find the beautiful thing. The same God who is a God of vengeance, is the one who sent his only son, Jesus, so that we who are guilty—we who ought to receive God's vengeance—can be delivered from it. This is why, while a man breathes, there is always hope that he will come to his senses and follow Christ.
