Adeline,
Are you a new convert? A baby Christian? I appreciate your zeal in defending the Christ, but there are wrong statements of yours I have seen. Jesus is GOD. You should refer to Christians only forums about these issues, otherwise muslims will turn around and say that you are shooting yourself in the foot.
Furthermore, Gospel Of Thomas is of Gnostic origins, and if you're familiar with the NT epistles you'd note that the apostles were strongly against Gnostic teachings (which are not revelations from God and neither are they consistent with the Gospel). Read more here:
