Who is Satan? Why is he allowed to exist? What do we know about him?
I understand at one time Satan was an angel in Heaven, the most beautiful. I have often wondered where his sin derived from to want to "take over". As I understand it, he was the one to start "tempting" to cause Eve to sin, but what caused his sin to become what it led to?
What is the correlation/connection between water baptism and church membership? I see where Acts 2:41 references both baptism and adding to the church in the same context, but have not found where baptism is clearly required for church membership.
