14 For what is your life? He might have checked this foolish license in determining things to come by many other reasons; for we see how the Lord daily frustrates those presumptuous men who promise what great things they will do. But he was satisfied with this one argument, who has promised to thee a life for tomorrow? Canst thou, a dying man, do what thou so confidently resolvest to do? For he who remembers the shortness of his life, will have his audacity easily checked so as not to extend too far his resolves. Nay, for no other reason do ungodly men indulge themselves so much, but because they forget that they are men. By the similitude of vapor, he strikingly shews that the purposes which are founded only on the present life, are altogether evanescent.
