10.Thou art a teacher of Israel. As Christ sees that he is spending his time and pains to no purpose in teaching so proud a man, he begins to reprove him sharply. And certainly such persons will never make any progress, until the wicked confidence, with which they are puffed up, be removed. This is, very properly, placed first in order; for in the very matter in which he chiefly plumes himself on his acuteness and sagacity, Christ censures his ignorance. He thought, that not to admit a thing to be possible would be considered a proof of gravity and intelligence, because that man is accounted. foolishly credulous who assents to what is told him by another, before he has fully inquired into the reason. But still Nicodemus, with all his magisterial haughtiness, exposes himself to ridicule by more than childish hesitation about the first principles. Such hesitation, certainly, is base and shameful. For what religion have we, what knowledge of God, what rule of living well, what hope of eternal life, if we do not believe that man is renewed by the Spirit of God? There is an emphasis, therefore, in the wordthese; for since Scripture frequently repeats this part of doctrine, it ought not to be unknown even to the lowest class of beginners. It is utterly beyond endurance that any man should be ignorant and unskilled in it, who professes to be a teacher in the Church of God.
