Martin Luther's emphasis on the claim that forgiveness of sin is entirely a gracious (free) gift from God, and that humans can do nothing to earn or even prompt this gift, sets Lutherans' narrative of salvation off from that of many other Christians.
Ultimate Reality and Divine Beings
Lutherans believe in God, Jesus Christ, and angels. Some Lutherans continue to believe in angels, while for others they seem implausible or simply irrelevant.
Human Nature and the Purpose of Existence
Human nature was created good, but is sinful, that is, fundamentally self-centered, as a result of the fall. The purpose of existence is to enter heaven, which is possible only through God's free forgiveness for sin.
Suffering and the Problem of Evil
The origin of suffering and evil for Luther was to be attributed solely to human sin, a result of the work of the devil.
Afterlife and Salvation
Martin Luther believed in a traditional idea of an immortal soul that spent eternity either in a literal place of blessedness called heaven or a literal place of torment called hell. Your destination depends on whether or not you are saved, that is, by God's grace forgiven for sin.
