Before we go into this subject I suggest you read my post on preexistence. When you do you will better understand what Jesus meant when He said, "Before Abraham was, I am." Jesus was in the mind of YAHWEH before the foundation of the world in the same way you and I are and all that we see in creation. Jesus is the Lamb that was slain before the foundation of the world, in YAHWEH's mind according to His eternal plan. Jesus was literally slain 2000 years ago. When Abraham was made the promise of his seed (Jesus) being blessed, Abraham believed YAHWEH and saw that day of the coming Messiah, the Christ, Abraham's seed. Galatians 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. Abraham saw this coming day and rejoiced. John 8:56-58 Your father Abraham rejoiced to see my (Jesus') day: and he saw it, and was glad. Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham? Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. The Jews proudly esteemed Abraham as being their father. John 8:31-33 Then said Jesus to those Jews which believed on him, If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free. They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free? Jesus, the coming seed of Abraham was planned way before Abraham this is why Jesus told the Jews, "Before Abraham was, I am." I AM, is not YAHWEH's true name for ever and He clears this up for us in the same verses where He says, "Tell the children of Israel, The Lord God of your fathers, the God of Abraham, the God of Issac and the God of Jacob has sent you. This is YAHWEH's name forever, not I AM. So why do we say that every time Jesus and only Jesus says, I am, He is referring Himself to be YAHWEH. It's a denominational, theological mindset that's all. Exodus 3:14-15 And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. 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.
