It is written in Deuteronomy 32:35: "With Me (is) vengeance, I will repay," says the Lord God. God will execute final justice by means of the Lord Jesus Christ at the time of his revelation from heaven. Vengeance can also be carried-out today against our bad behavior so that we are living in obedience to God and His Word. This study focuses on God's viewpoint regarding the execution of justice and that it is fearful to fall into the hands of the living God.
