oh Grasshopper...you have not even learned to snatch the pebble from the hand....and yet you want to teach..
just believing in God does not make you a Christian.......
A Christian can be of many denominations....it is about believing that Jesus Christ is the son of God....he suffered and died for our sins to allow us eternal salvation....(and hears the important part)...truly BELIEVE in HIM and you may someday enter His Kindom in Heaven.
now...pray tell...what is evil about that?
