Atheism is the rejection of belief in the existence of any gods, the claim that any gods do not exist or the absence of belief in the existence of any gods. But atheism is not merely the removal of gods from the equation; it is the exchange of God for something else. And it is the exchange of truth for a lie. Paul writes:
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, because that which is known about God is evident within them; for God made it evident to them. For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. Professing to be wise, they became fools, and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures.
Paul writes that unbelief produces an exchange. The word allaso means to exchange one thing for another. To exchange, in this context, is to displace one thing and swap it for another. What is being displaced is knowledge of God since the “the glory of God” refers to the manifestation of God’s attributes of “eternal power and divine nature.” And what is being installed in its place is creaturely. By creaturely I mean that it is a created thing. This is implied by the contrast of the incorruptible God with corruptible creature. Furthermore the thing installed in the place of the knowledge of the glory of God is “an image in the form of” a creaturely thing.
Unbelief, therefore, is not synonymous with lack of knowledge. Knowledge of the truth is clear and understood by all human beings. Some human beings, however, suppress what is clear and understood. This is the nature of unbelief; it is not innocent ignorance, but willful denial of the truth that has been made clear and has been understood.
The consequence of such unbelief is not a void, God is not merely displaced, but the truth that is clearly shown and understood is exchanged for another item, the image of which is abstracted from within the created order.
There is, therefore, no possibility of a lack of religious commitment only the possibility of a true religious commitment or a false religious commitment.
