Of old have you laid the foundation of the earth: and the heavens are the work of your hands. They shall perish, but you shall endure: yea, all of them shall grow old like a garment; as a vesture shall you change them, and they shall be changed: But you are the same, and your years shall have no end. (Psalm 102:25-27)
I the LORD, the first, and with the last; I am he. (Isaiah 41:4)
Knowledgeable christians should recognise portions of these passages. The Jesus-worshippers among them will say that the new testament books of Hebrews and Revelations applies these passages from the Jewish Bible to Jesus. They will say that since these passages talk about God in the “old testament” and the new testament applies them to Jesus, therefore Jesus is God.
Amazingly enough, these texts refute the very idea that Jesus could be God.
Both of these passages say a similar thing. They refer to the eternity of God. That means the timeless nature of God. God created time, he is outside of its power.
To be outside of time means that God’s nature is exactly the same way right now as it was back thousands of years ago. It will be exactly the same thousands of years in the future. At any moment in time, God can say “I’m the same one,” or “I am he.”
The same cannot be said for a human. Humans grow older. We start this life stupid, lacking understanding and knowledge. We grow, change, mature. I’m not the same person I was when I was born. My knowledge, maturity, size and capacity has changed as well as many other things about me. I can’t say “I am the same” as the person I was when I was born.
Now look at the Jesus presented by the new testament. He wa born, he grew up, he grew in wisdom, his body and mind changed over his life according to the new testament. His body was also changed due to injury and death. That dude was like any human, changing, maturing, etc.
Comparing the changeless, eternal, timeless God with the changing, growing, developing Jesus, stuck in time as any human, it is plain to see that Jesus was not God at all!
