And God said moreover unto Moses, Thus shalt thou say unto the children of Israel, The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations.Exodus 3:15
When God revealed Himself to Moses, He declared that it would be by the name of THE LORD GOD of Abraham, Isaac, and Jacob that HE would be remembered in memorial forever. He was not just referring to the title, but the Person in whom His people would remember the name revealed to Abraham, Isaac and Jacob. Even without the rest of Scripture, by the Spirit of God, there is enough revealed in this one scripture to know that this is God revealing to Moses the Person and Work of the LORD Jesus that He would come and accomplish millenniums later, in the fullness of the time, and whose life and death would serve as a memorial before God and His people of the salvation that He wrought for their salvation.
How do we know that this revelation of God to Moses is fulfilled in the LORD Jesus Christ? Many portions of Scripture declare it is so:
Exodus 3:6-Moses and the burning bush.“Moreover he said, I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. And Moses hid his face; for he was afraid to look upon God.” Here was given to Moses what is called a ‘theophany,’ or, a visible manifestation of God. We know that none can look on the face of God and live, apart from a Mediator. Therefore, it must be none other than the LORD Jesus speaking here to Moses in the burning bush, a fire that burned but did not consume the bush. So it is with the person and work of the LORD Jesus. He grew up as a root out of dry ground, and suffered the penalty of the wrath of God for the sin of His people, and yet was not consumed by it. It destroyed the sin and not the Savior. It consumed the sacrifice and the wood upon the altar, (Christ’s body in which HE suffered unto death) but not the altar (Christ’s divinity).
John 8:58- Christ confronted by the Pharisees- “Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.” If any question whether Christ is God in the flesh, or whether He is the one who first revealed Himself to Abraham and in Abraham, doubt no more. He is the God of Abraham, Isaac, and Jacob need merely in title, but IN DEED. He is the promised seed [Galatians 3:16], and He is their God, in that, by His Spirit they were caused to look outside of themselves to Him who was to come, and did come in the fullness of the times. Our LORD declared, ‘Abraham rejoiced to see my day: and he saw it, and was glad,’ John 8:56. As the God of Abraham, Isaac, and Jacob, the Spirit of Christ was in them to look outside themselves to Him who is the promised seed. So it is with all of His chosen, redeemed ones, in whom He reveals Christ in His time.
Matthew 22:32-Christ confronted by the Sadducees.I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. At the time that God (Christ) made this declaration to Moses for time memorial, Abraham, Isaac and Jacob were already dead and buried. Yet, He declared ‘I AM,’ not I was. Even as our LORD told the Pharisees, before Abraham was, ‘I AM,’ not I “was.” And again in John 8:24, I said therefore unto you, that ye shall die in your sins: for if ye believe not that I AM he, ye shall die in your sins.” None can live apart from the LORD Jesus and His finished work on their behalf, whether in the Old Testament or since the first coming of the LORD Jesus. In Him and by His death alone all who are the LORD’s, Old and New Testament live. All of the LORD’S own were redeemed and justified in one place, one sacrifice, and one way. He is the God of Abraham, Isaac, and Jacob, and He is therefore MY God and Savior. There is none other.
