There are some atheists who do not think that their atheism has much impact on their lives as a whole. To them, atheism (or the lack of belief in God or the Supernatural) is but a small part of their lives. They might even compare a lack of belief in God to a lack of belief in Santa Claus or unicorns. But is it really true that atheism has little impact on one’s life? Definitely not! Let me briefly trace the consequences of atheism, and particularly of denying the God of the Bible, in three areas.
First, atheism has an impact on one’s view of reality. Most atheists would say that reality is composed of the material and physical, and that nothing beyond space and time exist, and even if it does exist, it has no impact on his life. As such, everything that the Bible says about the origin and purpose of this universe, of life, man, angels, heaven, hell etc can be discarded.
Second, atheism has an impact on one’s view of knowledge. If, as most atheists would say, reality is simply what can be experienced by the senses and nothing else, then they have determined the only method of knowing, namely, through observation. Revelation from God, i.e. the Bible, is ruled out, a priori, as a valid source of knowledge and truth.
Third, atheism has an impact on morality, i.e. it has implications for how a person lives and how he will determine right and wrong. If God does not exist, then everything that the Bible says about what God requires of man can be discarded. The atheist is essentially saying that he is his own “God” and that he will determine for himself what is right and wrong, and what the course of his life ought to be. He will use his own common sense or any other ethical theory devised by man to judge good and evil, right and wrong.
It’s clear that all atheists have a philosophy of life that is radically affected by their rejection of the supernatural. It’s true that there is no common philosophy among all atheists but one thing is sure, they have all rejected the Biblical philosophy of life and substituted something else for it.
The Bible has this to say about atheists: “The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good. (Psalm 14:1)” And again: “And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are no convenient…(Rom. 1:28)”
