One of the goals of Apologetics is to deal with the objections that people have regarding the existence of God. For the last several weeks, we have been listing some of these objections and the arguments that address them. Here is where we address the “only a logical existence” of God:
Only a Logical Existence. Some antitheists argue that it is logically necessary for a triangle to have three sides, but it is not necessary for any three-sided thing to exist. Even if it were logically necessary for God to exist, that does not mean he actually does exist.
At best, this is an objection only to the ontological argument. Theists need not, and most theists do not, conceive of God as a logically necessary being but as an actually necessary being.
It is logically possible that no triangle exists, but if it does exist, it actually necessarily has three sides. It is logically possible that there is no Necessary Being. But if a Necessary Being exists, then it is actually necessary for it to exist. For a Necessary Being must exist necessarily.
