Alas! said Luther, what is our wit and wisdom? for before we understand anything as we ought, we lie down and die; therefore the devil hath good striving with us. When one is thirty years old, so hath he as yet Stultitias carnales; yea, also Stultitias spirituales; yet it is much to be admired that, in such our imbecility and weakness, we achieve and accomplish so much and such great matters; but it is God that giveth it.
