There were three requirements that had to be met for the Son of God to be made man. First, the one who was to become a man already existed as a person. Only a body was needed, not a new person. Second, it was necessary for the Son of God to be fully related to us as a man. Third He had to be without sin—fully related to us, yet without sin! The Scriptures tell us how God brought His Son into our flesh in a way that met all the requirements.
