While on Earth the Lord Jesus acknowledged Himself as Jehovah of the Old Testament: “except ye believe that I Am, ye shall die in your sins” (John 8:24). He told us He is the “I AM” (John 8:28); and again: “verily, verily, I say unto you, Before Abraham was born, I Am” (John 8:58). He clearly declared that He is Jehovah, and the Jews themselves clearly understood it, for it was because of this statement they took up stones to cast at Him Jesus.
To put it more clearly, however, the name of God as “I am that I am” shows us at least 2 reasons for His commands:
1) I am – That is to say, I am powerful, therefore you should not do anything. I am your power, protection, holiness, righteousness and supply. Hence you have no need to sin. You say you have passions and lusts in you, but Jehovah declares: “I am righteousness and holiness.” So why must you sin. You say you have no money, so you ask for a loan; but Jehovah says to you “I am your supply.”
2) “I am” – That is to say, I am not only your power and wisdom who loves you dearly and has chosen you, I am also Jehovah God who will hasten you if you do evil. So that, yes, I am is first of all-powerful; but second of all, He will judge. First, He is the most powerful in being our righteousness and holiness; but He will judge us according to His righteousness and holiness. When He uses the name Jehovah – the “I am that I am” – He does not bother to explain the reason for His commandments. He simply tells People, “I am Jehovah.” I am Jehovah; therefore you must do or not do various things.
God says, “I am the God of Abraham, the God of Isaac, and the God of Jacob” Why does God not declare Himself as the God of Adam? For we know that Abraham sinned even as Adam did. Why then did He not call Himself the God of Adam? Why instead did He call Himself the God of Abraham, and Isaac, and of Jacob? Why was it that the Lord was presented as the seed of Abraham? Why from all the men should God have called have called Himself these three particular persons? Other than the fact, that God had made a covenant with each of these men. He takes them as representative persons. He uses them to represent the three types of men in the world.
What type of man is Abraham? He is a giant of faith. He is rather uncommon: in fact he is quite special. As the God of Abraham, God decrees Himself to be the God of excellent people. But He is not only the God of the excellent. Were He merely this kind of God we would despair because we are not persons of excellence. But God is also the God of Isaac. What type of person is Isaac? He is very ordinary. He eats whenever he can; he sleeps as he has opportunity. He is nether a wonder man or a wicked person. Yet God is not only the God of ordinary men, He is also the God of the bad men: He is the God of Jacob too, for in scripture Jacob is pictured as one of the worst persons to be found in the Old Testament.
So God is telling us that He is the God of excellent people, the God of ordinary people and the God of the worst people. From that day in Exodus onward, God has always called Himself by that wonderful name. Even when the Lord Jesus was about to face death, He said this: “as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham, Isaac and Jacob? God is not the God of the dead, but of the Living” (Matt. 22:31-32). Here the Lord adds one more meaning to that name. When God calls Himself by such a name, it reveals the fact that He is also the God of resurrection.
So, that in the resurrection realm, God is to be the God of these three men. This indicates to us Christians, weather we are naturally talented, ordinary, or bad, that we will all decay; nevertheless, Our God will re-create us and make us new in Him. Though we are so different in the natural, God will eliminate all the differences and be our God all the same. For what He looks at is not our natural endowment but the life He has given us.
