John 10:31 Then the Jews took up stones again to stone him. 32 Jesus answered them, many good works have I shewed you from my Father; for which of those works do you stone me?
John 10:33 The Jews answered him, saying, for a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God…. When some believers declare themselves to be New Testament Christians only, they may not know that it is primarily Christ that is being referenced in the Old Testament as God. When you sing the song Jehovah Jireh, that is Christ you are singing about. Jehovah-Nissi is also a reference to Christ.
It was Christ who came looking for our first parents in the cool of the day, after they had sinned. It was Christ who made them the promise “It shall bruise thy head, and thou shalt bruise his heel.” The God in the burning bush, who appeared unto Moses, was Christ. When you read in the Bible of The God of Abraham, Isaac, and Jacob, those are references to Christ. To put it plainly, God the Father, basically has nothing to say to the human race, except what He says in, and through Christ.
It was Christ who spoke the law on mount Sinai, and it was Jesus who throughout the Old Testament, and into the New Testament is represented primarily as the God of the Bible. Thus, to reject the Old in favor of the New is to literally reject both Old and New, because Christ is God from eternity to eternity. Jesus did not become a God at some distant point in the past neither was Christ elevated or graduated to be God.
Psalms 90:2 Before the mountains were brought forth, or ever thou had formed the earth and the world, even from everlasting to everlasting, thou art God.
May The Lord add His blessing to the study of His word. God bless!
