Wenham, Christ and the Bible (1984):
There is a beautiful consistency about the paradox [of the incarnation.] That the humanity of Christ is depicted in the Gospels as fully and clearly as his divinity needs no documentation. Jesus is seen as the Last Adam, as Ideal Man in perfect communion with God. God, on the one hand, is all powerful, all holy, all knowing; unable to fail, unable to sin, unable to err. Fallen man, on the other hand, fails, sins, errs. Ideal Man, however, could-but-does-not-fail, could-but-does-not-sin, could-but-does-not-err. Jesus tasted human weakness to the limit, but did not fail; experienced temptation at its fiercest, but did not sin; shared human ignorance to the full, but taught no error.
