The land of a certain rich man was very productive. And he began reasoning to himself, saying, “What shall I do, since I have no place to store my crops?” And he said, “This is what I will do: I will tear down my barns and build larger ones, and there I will store all my grain and my goods. And I will say to my soul, ‘Soul, you have many goods laid up for many years to come; take your ease, eat, drink, and be merry.’” But God said to him, “You fool! This very night your soul is required of you; and now who will own what you have prepared?” So is the man who lays up treasure for himself, and is not rich toward God. (Luke 12:16-21).
Do not lay up for yourselves treasures upon earth, where moth and rust destroy, and where thieves break in and steal. But lay up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in or steal; for where your treasure is, there will your heart be also. (Matthew 6:19-21).
For what will a man be profited, if he gains the whole world, and forfeits his soul? Or what will a man give in exchange for his soul? (Matthew 16:26).
