In Christian Science we learn the wonderful truth that God gives each of us divine authority over the temptation to sin. God made us to be, and see, our sinless spiritual selfhood, and we can demonstrate this in our experience. 

Both sins and mistakes cause trouble. But a mistake is usually unintentional, a thought or action resulting from ignorance, bad judgment, or carelessness, whereas sin is a conscious act—intentional wrongdoing. 

Mistakes can be corrected by knowledge or discernment. Sin, however, is eradicated by recognizing that our motives and actions were wrong and refusing to think or act in the same unloving, harmful, or self-destructive way. Several Bible accounts depict Jesus healing by exposing and destroying sin.
