Consider the following incident mentioned in the Bible:
"And behold, one came and said unto him, 'Good Master, what good thing shall I do, that I may have eternal life?'
And he said unto him, 'Why callest thou me good? There is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.' "
Jesus (pbuh) did not say that to have the eternal life of paradise, man should believe in him as Almighty God or worship him as God, or believe that Jesus (pbuh) would die for his sins. On the contrary he said that the path to salvation was through keeping the commandments. It is indeed striking to note the difference between the words of Jesus Christ (pbuh) and the Christian dogma of salvation through the sacrifice of Jesus (pbuh).
