Seest thou how by that which is evident, He hath manifested that also which is obscure? Thus, “As unto thy body,” saith He, “thou wilt not by taking thought be able to add, though it be ever so little; so neither to gather food; think as thou mayest otherwise.” Hence it is clear that not our diligence, but the providence of God, even where we seem to be active, effects all. So that, were He to forsake us, no care, nor anxiety, nor toil, nor any other such thing, will ever appear to come to anything, but all will utterly pass away.
