We humans know the feeling and the power when we learn something like learning to read and write, to walk, to drive, to speak, you name it but have you ever wondered how is it for God to be a man ( we have to use our imagination).
Imagine our Creator to be a creature. From infinity to finite. From being the most powerful and all knowing God to being a hapless baby. From Spirit to having a human body. From without limit to accepting limitation.
Believe it or not it happened in the person of Jesus Christ. He is the God who became man to save us from our sins.
If you want to know the details open your Bible and see it unfold before your eyes.
