Christianity is unique because of the uniqueness of Christ our Lord. He alone is both God and man. He alone could, by His own death, pay the penalty for the sins of the world and thus fully satisfy the demands of divine justice. And in contrast to Buddha or Muhammad or other religious leaders, whose graves contain their decayed remains, the grave of Jesus is uniquely empty. He alone conquered death and promised His disciples, "Because I live, ye shall live also" Everything we have is in Him and Him alone and thus depends entirely upon our relationship with Him.
