You have asked much from me, a human being. My first thought is that I will not write the correct thing to help you if you sincerely care to seek salvation and a relationship with God. One thing you must understand is that many churches and many people have messed up and done what they thought was right but what was wrong in God's eyes. This fact understandably turns people away from God. You will not find the perfect church, for only God is the perfect church. You seek evidence that God exists. He exists because you keep chasing Him. You note a void in your life that you cannot seem to fill. You know it is God, because you keep resisting Him. He is the gentle breeze, the beautiful mountain, the inexplicably logical math problem, an innocent child, and...finding someone to talk to like me. God has sent me to you for this brief moment. You are seeking, Evan. God says to seek and you will find Him.
