Some have a really funny sense of humor. It even makes me laugh out loud sometimes at the funny jokes (not the ones where they insult people).
Another reason I enjoy some of the agnostics/atheist is because it offers a different perspective on life. I believe in God, but I totally respect other people’s beliefs. I try to be friends and love all people regardless of their beliefs.
I try to take the opportunity to find out their individual beliefs, and why they believe what they believe. It all interests me.
Another thing I really like about them, is that they ask tough questions. Many people accept a belief system on blind faith, and the first time something goes wrong in their life, they stop believing. This is because they never seek the answers to deep or complex questions about God. They have a very superficial belief system.
Yet many atheists on here bring up those questions, and I always appreciate it because sometimes it forces me to really think deep and find answers to those questions. When I find reasonable answers to those questions, it makes my faith in God grow deeper, and helps explain things in a more deep way.
