A common assertion is that the Bible presents two very different depictions of God. The God of the Old Testament is a God of wrath who flooded the earth, wiped out cities and commanded the destruction of nations. On the other hand, the God of the New Testament is shown through Jesus to be a God of love. He is patient, ready to forgive and tender towards sinners. Does the Biblical presentation of God change from the Old to the New Testament?
Describing the God of the Old Testament as a God of wrath and the God of the New Testament as a God of love is a caricature. The Bible gives a uniform description of God. The God found in Genesis is the same God found in Revelation. God does not change. His character and purpose has remained the same throughout the history of mankind.
The God the Old Testament is a God of great love. When God showed a portion of His glory to Moses He declared Himself to be, “The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth, Keeping mercy for thousands, forgiving iniquity and transgression and sin.” (Exodus 34:6-7) The Psalms are full of descriptions of God’s love. “The Lord is gracious, and full of compassion; slow to anger, and of great mercy. The Lord is good to all:and his tender mercies are over all his works.” (Psalm 145:8-9)
Even in times of terrible judgment the compassion of God is evident. In the book of Lamentations the prophet Jeremiah weeps over the destruction of Jerusalem. Yet he says, “It is of the Lord’s mercies that we are not consumed, because His compassions fail not. They are new every morning: great is Thy faithfulness.” (Lamentations 3:22-23) God’s love was not restricted to the Israelites. The prophet Jonah did not want to preach in Nineveh because he knew God is “a gracious God, and merciful, slow to anger, and fo great kindness.” (Jonah 4: 2) Jonah hated the Assyrians, God did not. God rebuked Jonah for his callousness towards the Ninevites. God asked Noah if He should not spare Nineveh that had 120,000 children? Just like with Sodom and Gomorrah God was ready to forgive and hold back His judgment. From the very beginning of the Old Testament God shows Himself to be a God of great love.
The God of the New Testament is a God of wrath. Consider Jesus’ stern warnings about hell. He said in Matthew 25 that all those who are not His followers will be condemned to everlasting torment in hell. “And these shall go away into everlasting punishment: but the righteous into life eternal.” Jesus promises the most terrible judgment on unbelievers. He is clearly a God of wrath.
The wrath of God is not only found in the gospels. Romans 1 warns “The wrath of God is revealed from heaven against all ungodliness and unrighteousness of men.” Colossians 3 teaches the Christian to put aside sinful attitudes. “For which things sake the wrath of God cometh on the children of disobedience.” The book of Revelation is filled with the wrath of God and the judgment of Jesus. The severity of the judgments in Revelation rival anything found in the Old Testament. In Revelation 19 Jesus is described as descending from heaven. “Out of His mouth goeth a sharp sword, that with it He should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of the Almighty God.” The Jesus of the New Testament is the God of judgment who executes His wrath upon all the lost.
The God of the Bible is the same throughout. Jesus and Jehovah are not two different Gods, or two different personalities of God. They are the same God who pardons and punishes sin. His love and His wrath are equally functions of His holiness. He is the Holy God, Sovereign over His creation, exercising justice and mercy, showing love and wrath, giving grace and punishment, to all. He is God who does not change.
