Hello Atheists... Are You Thinking?
Although Christianity is logical and rational, I'm not saying that Christianity or the Bible is needed to arrive at this conclusion. The claim of atheism, standing on its own, is a claim that god exists -- and it is a statement that the person making the claim of atheism is not rational.
Because to claim atheism is to claim that you are omniscient... a claim that you know everything. A claim of having all knowledge. To know that God does not exist means that you have to know he does not exist anywhere beyond our solar system. An atheist must know every detail about everything in our galaxy in order to know God is nowhere in our galaxy. They need to know everything about the physical universe to know that God exists nowhere in the universe. They need to know everything about everything that exists outside of the universe to know God does not exist in a spiritual realm or fifth dimension or wherever. In order to know that God does not exist a atheist is claiming to know EVERYTHING. Who is the only one who can know everything? God. So an atheists' claim to be an atheist is a claim to be god themselves, and thus it is a claim that god exists. It's a claim that contradicts itself.
A rational person can be an agnostic. An agnostic is a person who claims to not know whether there is a god or not. That is a rational claim. So if you don't know whether there is a God or not, is it not worthwhile to find out more? Because if there is a God, and you are going to be judged by that God when you die, it is very important to learn about that and understand it now... because when you die it is too late.
