The bible calls people who deny God’s existence fools (Ps.14:1; 53:1). Without evidence, they say there is no living God. These people are atheists. The reason it is foolish not believing in God is because of all the evidence God has provided for his existence. The universe itself proves God exists. Everything in our created world has a beginning and the universe is no exception. There was a time when the universe did not exist. To bring it into existence out of nothing takes supernatural power that is beyond the limits of our natural laws. This demands a supernatural being/God (Ps.19:1; Rom.1:19-20). Only the foolish deny this. Another type of fool is someone who believes in God but denies him in their actions. An unfaithful believer is an unbeliever. “They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate” (Tit.1:16). The atheist and unfaithful believer have the denial of God in common.
Next, life is quick, and death comes soon (Ps.102:2,4; Jas.4:14; 1 Pet.1:24). God is eternal, “from everlasting to everlasting,” so time is irrelevant to him (Ps.90:2,4). But this is not the case with man. Our days on earth are generally numbered under 100 years and the longer we live the more difficult life becomes (Ps.90:10; Eccl.12:1). Yet, no matter how long we live, or how long anyone has ever lived, “it is soon cutoff, and we fly away” (Ps.90:10). Methuselah, who is the longest living person recorded in the bible, lived to be 969 years and death came to him “soon” as well. What is thousand years compared to eternity? Nothing at all. Death will soon come to all the living and the foolish are not right with God. What will happen to all the earthly riches the foolish have accumulated? Jesus told a parable about a rich man who stored up riches for a long good life but was not rich toward God.
“But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided? So is he that layeth up treasure for himself, and is not rich toward God” (Lk.12:19-21; 1Tim.6:7). Fools and their riches are soon parted. “What shall it profit a man, if he gain the whole world, and lose his own soul?” (Mk.8:36).
Therefore, the wise give themselves to God and lay up spiritual riches in heaven (Mt.6:19-20). The wise will never be separated from the riches they have. The riches of no more pain, no more sorrow, no more crying, no more hunger or thirst, and no more death (Rev.7:16-17; 21:4).
