We’re using the book “Handbook of Apologetics” by Peter Kreeft and Ronald Tacelli to go over the arguments for the existence of God. We will now begin covering the attributes of God. Dr. Kreeft teaches logic in two major universities, so his arguments tend to be clear, concise and very helpful.
This week we’ll go over God Exists Absolutely:
By this we do not mean merely that God is always there or that he does not tend to go out of existence. These things are true, in a sense. But we mean something more.
God is the source of being, or existence, for all things. Looking at the universe we see that in every creature there is a distinction between its essence and its existence; that there is a difference between what things are and the fact that they are. That is why, as we saw, limited things are by nature existential zeros, why they have a need for being that they cannot themselves supply.
If God is the answer to this question about finite being, then he cannot suffer from this same need. In other words, in God there can be no such distance between what he is and that he is. That he exists is not a happy accident, not due to some other being as his cause. Being must be inseparable from what he is; it must belong to him by nature. More radically put: God must be identical with the fullness of being. That is what we mean by saying that God exists absolutely.
