Augustine of Hippo, on Ps 145:4

“His spirit shall go forth, and he shall return into his earth: in that day all their thoughts shall perish.”

“The Apostle says, "I am afraid that just as the serpent deceived Eve with his cunning, so your minds may be corrupted from the chastity which is in Christ." But their minds are corrupted by such conversations: "Let us eat and drink, for tomorrow we die." Those who love these things, who pursue these things, who consider this life alone to be, who hope for nothing beyond, who either do not pray to God or pray to Him for these very things, for whom the discourse of diligence is burdensome, let them hear us say these things with great sadness. They want to eat and drink; for tomorrow they die. If only they truly thought that they would die tomorrow. For who is so mad and perverse, who is so much an enemy of his own soul, who, dying tomorrow, does not think that all things for which he labors will have ended? For it is written: "On that day all his thoughts will perish." Even if men take care in drawing up a will on the imminent day of their death for the sake of those they leave behind, how much more should they think of their own soul? Man considers whom he will leave behind, but he does not think of himself who leaves all these things behind.”
