There are two ways to interpret this question. One is to ask whether or not belief in God or the idea of God is logical. The other is to ask if God Himself is a logical being. The answer to both is, “Yes, God is logical,” for similar reasons.
It’s logical to believe in God because the existence of God provides consistent answers to many of the more important philosophical questions asked by human beings. For instance, we know that there cannot be an infinite amount of past time; it is illogical to claim we are currently at the “end” of an infinite string of moments. Therefore, there had to be some beginning moment in time past for the creation. Therefore, there has to be something, some cause that is itself non-caused. Logically, this is God. Thus God has always existed which finite minds cannot reason.
Another reasonable belief that God is logical is that the universe or cosmos appears to be carefully crafted and ordered to allow all matter, time, energy and life. Not only that, but this arrangement allows for the kind of life that is complex enough to be self-aware. Ultimately, there are only two explanations for this: either some kind of God or random chance. And punting to “chance” has never been a very logical answer, except for the atheist’s theory of Evolution, which makes no sense, for the DNA of one species, could never create the DNA of another species. However, this never stops the atheists from believing in it. Their false Ideology always trumps the truth, especially God’s truth.
The fact that human beings think of “logic” at all, also supports the idea of God as a rational belief. If God does not exist, then there is no intelligence, purpose, or meaning in anything, especially human life. Atheists believe human intelligence, purpose, and meaning are simply illusions created by physics and chemistry. However, if there is no God, it would also mean our reason, intellect, and learning are mere illusions of the human mind. However lacking God, there is no logic. There is no reason to think our thoughts are meaningful or that they actually reflect reality. Our thoughts may be good for survival or simply the results of randomness or self-preservation, but they can’t be relied on as true. However, in short, the only way to believe that there is such a thing as logic is for one to believe in a God, who created everything, seen and unseen, known and unknown.
Another key point is that those who believe in the laws of logic are confident in something objective, eternal, and non-material. Any objection that God is real, eternal, or objective would be hypocritical coming from someone who puts stock in the laws of logic.
We also know that God Himself is logical, based on His written Words and His actions. First and foremost, God acts in a logical way: He plans, communicates, discusses, and acts. God even speaks of “reasoning” with human beings (Isaiah 1:18). He distinguishes between truth and falsehood, a core aspect of basic logic (John 7:18). God does not always act in ways human beings would prefer, but this does not mean His actions are “illogical.”
Also, the fact that there are certain things God “cannot” do, such as lie or change, or let you in His heaven unless you are spiritually Born-Again, is evidence of His logical nature. A truly perfect infinite being, by definition, cannot change or he ceases to be perfect. This means God cannot contradict His own nature, or else He would be breaking the laws of His logic.
Of course, all of these ideas involving God and His perfect logic will never be accepted by atheists who are anti-God and live according to their innate sin nature and thus are followers of Satan.
