Sin enters the world through humanity's disobedience and desire for things forbidden. Sin dwells within people and is tempted outward by one's own lusts and enticements. When desire is conceived, it gives birth to sin, which leads to death. The three sources of sin are the lust of the flesh, the lust of the eyes, and the pride of life. While Jesus was tempted in every way, he did not sin and offers forgiveness for humanity's sins, transgressions, and iniquities.
