What is logical for man is not always the truth, but I would contend that such is not really logic. For example, many think man evolved from apes. They think that it is logical, but I contend that this proposition is illogical.
Logos is often viewed as an appeal to logic and there are some things that are logical that upon denial, demonstrate that a person is deluded. If God created all things through the Logos, then that could imply that the physical universe is logical.
It is absolutely logical for example that there is a God and denial of that is without excuse because that truth is self evident. It is logical to assume that created things imply a creator. Mathematics is an example of logic and in describing the physical universe it appears to always work. We often apply logic everyday to get by. e.g., at 5:30 pm it will take me longer to get home because of the traffic. As for spiritual things, logic alone is not apt to work. Love cannot be defined by mere logic, it is beyond that and should be the base of all.
