The only religion in the world that offers salvation by grace (unmerited favor); all the rest require good works. In Christianity good works merely prove that an individual has faith (faith being the only requirement by Jesus Christ). Jesus Christ died for the sins of mankind because of His love for them in the same way that a parent will gladly give up his or her life for a child. Christianity is based on the death and resurrection of Jesus Christ, God's only begotten Son. Jesus Christ is of the same substance as His father. As a human begets a human, so God begets God.
Because of the nature of Christianity, the only true followers are those that are of a contrite spirit and are willing to die for their faith. Real Christians pray for their enemies and do not take revenge.
