Is God different in the New Testament?

Question: "Why is God so different in the Old Testament than He is in the New Testament?"

Answer:
At the very heart of this question lies a fundamental misunderstanding of what both the Old and New Testaments reveal about the nature of God. Another way of expressing this same basic thought is when people say, “The God of the Old Testament is a God of wrath while the God of the New Testament is a God of love.” The fact that the Bible is God’s progressive revelation of Himself to us through historical events and through His relationship with people throughout history might contribute to misconceptions about what God is like in the Old Testament as compared to the New Testament. However, when one reads both the Old and the New Testaments, it becomes evident that God is not different from one testament to another and that God’s wrath and His love are revealed in both testaments.
