What does Luther say happens to a person's sins when he or she dies?

Answer with Explanation:

Before Luther's Reformation, he thought that a person's sins could deny him of his salvation when he dies. It was also a proof that he wasn't faithful or loyal enough to the Lord.

However, such conviction of his changed after witnessing some events. He questioned the Pope's ability to set the Christians free from suffering. With this, he realized that sin was not a moral failure. People have been born in order to die and for him, this is the meaning of "sin." In order not to lose in the battle of death, one must be "baptized." This is the option given by God to humans.

Thus, this explains the answer.
