Godly figures were introduced later. The Muslims also believe in one god known as Allah. On Salvation Man lives his own fate, and has no one to blame but himself. Salvation is not based on work. It is a free gift to all who would accept Jesus Christ as their Savior.
Salvation is based on work through implementing the five pillars in life.
In a sense, there is eternal life. But one is not sure what his next life will end up being. It depends on the karma of his present life. Eternal life in heaven is promised to all who accept this free gift of salvation. Eternal life is defined as 'eternal bliss in Hereafter'.
