Well, first of the world totally needs to know about Christainity. It's an amazing religon, for my opinion. The Lord created us in His own image. He was a loving and gracious God, but we turned our backs on Him. He wanted us back so He sent His Son down to the earth to bring His people back to Him. He did that by dying on the cross. He forgave all of our sins and we can have eternal life with Him in heaven.
