I John 3:1a “The reason the world does not know us is that it did not know him.” Jesus is the Savior of the world.  If a person disagrees with that truth there cannot be an understanding of a Christian.  God forces no one to believe in Him.  Christianity is the only faith which believes one can do nothing to gain eternal life.  Good works are a direct result of a strong faith, but there is no such thing as self-righteousness.  All religions which require man to do something–like tithe, like pray a certain number of times per day, like anything to earn eternal life, like follow a set of rules, like failure to believe Jesus lived, died and rose.  Without this understanding a person simply does not know what Christianity is all about and does not understand what being a child of God is all about.  There is no such thought in Christianity which agrees with—-there is only one God however you see Him.  The true statement is:  There is only One True God as He describes Himself in Scripture.
