This issue arose on another thread - I wanted to raise it here where I hope there will be some good responses! I do not think that Jesus was not a man before the incarnation. The incarnation was all about Jesus becoming human, which is the same as becoming a man. That's another point, as the person disputing this said that being human and being a man are not the same thing, if I understood him correctly. When Jesus incarnated, he became a man by adding on a human nature and body. The main support for this is Hebrews 2. The OT appearances of Jesus, even if he appeared as a man, do not say or mean he became a man at that time. I am raising this here to clarify the issue.
