I believe that Jesus Christ is God come in the flesh (Joh 1:1, 14), therefore what is true of Jesus Christ is true of God — YHVH, Yehovah, the Lord. In the New Testament, it says that God is love (1 Joh 4:8). This is a common descriptor that is applied to the God of the New Testament, of God the Father and the Lord Jesus Christ.
But if Jesus Christ is the same yesterday that He is today (Heb 13:8), then it must also be true that the God of the Old Testament is love.
This is not a common descriptor that is applied to the God of the Old Testament. It is commonly said that the God of the Old Testament is vengeful, wrathful, judgmental, and angry. I have heard many Christian preachers say over the pulpit that God is not angry anymore, indicating that a distinction must be made between the God of the Old Testament and the God of the New, because the God of the Old is vengeful, wrathful, judgmental, and angry, while the God of the New is loving, forgiving, merciful, and gracious.
So is it true that the Scripture describes two different Gods, a God of the Old Testament who is different in nature and expression than a God of the New Testament? As I have studied this question, I have found one God, one faith, one gospel, and one people of God from Genesis to Revelation. I have found the God of love, and the gospel of salvation by grace through faith, inscribed throughout the pages of the Old Testament – and not just in a few places, but in every book, in overwhelming repetition.
Moreover, I have found that particularly the Torah, the first five books of Moses, expresses the nature of the God who is love. It is the Law of the God who is love. It is the Law of Love. Because we have misunderstood the unique way Torah “writes about Messiah” (Joh 5:46), we have misunderstood not only the Law, but the nature of the God of the Old Testament. In this book, I hope to prove from the Scripture that the Law of God is the Law of Love, which expresses the nature of the God who is love!
