There comes a time in every man's life when he must decide whether to save life or to kill, to do good or to do evil. However, sometimes doing the right thing has a higher cost than doing the wrong thing or not doing anything at all.
Jesus' life and ministry exemplified a life of doing the right thing at great cost. He would touch that which was forbidden to touch and heal when it was forbidden to heal according to the law of the day. But he did these things anyway because in his heart he knew it was the right thing to do. To act contrary to what you know to be right is in a word, sin.
Peter felt it's pain after denying Christ three times. I tell you the truth, the weight of guilt, remorse, and regret is far worse than anything man can do to you. To do what is right, to save a life, requires self-sacrifice whether it be your time, your money, your freedom, or your life. To simply do nothing at all for the sake of comfort is to forfeit potential good. MLK understood this well. Sometimes one must break all the rules in order to find shalom.
Therefore I say to you, do what is right even if it kills you. There are far worse things than death.
