'If anyone might be thought to have lived on auto-pilot, it would be Jesus. After all, along with his true and full humanity, he was fully God; and although he had the nature of a man, his human nature was totally sinless. You would think such a person (unlike any of us!) could coast. To have a divine nature and a sinless human nature would seem to make obedience easy. Well, look again at Jesus. What you see is a man who labored to obey, who agonized in the testings the Father designed for him, who fought through the trials of life to maintain his integrity and obedience before his Father.
In the light of this, it should be certain that we who are not God, we who do not have sinless natures, will find it necessary also to fight for faith and labor for obedience.'
Bruce A Ware, The Man Christ Jesus, p.70.
