And Jesus said unto him, Why callest thou me good? there is none good but one, that is, God. Mark 10:8
Christ was sinless but he recognized in himself at least the potential for going wrong out side of the envelope of oneness with the Father... he Knew his own humanity and his own frailties. He was tempted at all points, according to Paul.
There is human nature and there is divine nature. Jesus called us into divine nature. “Be ye therefor perfect even as your Father in heaven is perfect.” Mat 5/48.
