We Christians are called “crazy” because we believe in a being that we can not even see. This is why they brand us as irrational beings, fanatics, lunatics, etc. Well, it’s also crazy to think that there are aliens, life on other planets and flying saucers. I think it is more rational to believe in the existence of a being that created all things, well, it is also crazy to think that the world was created out of nothing.
The Bible says:
6 Therefore we are always confident and know that as long as we are at home in the body we are away from the Lord.
7 For we live by faith, not by sight.
8 We are confident, I say, and would prefer to be away from the body and at home with the Lord.
2 Corinthians 5:6-8
