Religion helps us understand that there is a Savior of the world. That means that regardless of what mistakes we've made, if we repent we can return to God. Because of the sacrifice of Jesus Christ, we can change our lives and God will forgive us. When we come unto Christ and are baptized, all of our sins or wrongdoings are washed away, and we can start with a clean slate. Because of religion, many have changed their lives for good and made a difference in the world.
