Every religion known to man has one thing in common...the struggle man faces to become acceptable to God, or to attain Heaven. Every religion, that is, except one. The Christian religion makes it clear that man is unable to reach Heaven, not one is without sin and worthy of God. With one exception, the man Jesus, the Son of God, God Himself. Only through the sacrifice of the only Son of God can mankind attain Heaven, and only by accepting that sacrifice and humbling oneself enough to accept the forgiveness of all your sins...through NO agency of your own, without any pride, without any works.
Every other religion is won through works, only Christianity is won through acceptance of a gift.
Every other religion is man's work, only Christianity is a relationship with the God that reaches down from Heaven to wash us and raise us up.
Every other religion was dreamed up by a man. Christianity is so bizarre, it could only come from a mind far above any man's.
