Parallel, Matthew 16:26 “For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?” Luke 9:25 “For what is a man advantaged, if he gain the whole world, and lose himself, or be cast away?” Satan thinks that man will give anything for his life–including his faith. Job 2:4 “And Satan answered the LORD, and said, Skin for skin, yea, all that a man hath will he give for his life.” So, he is going to try to get you to believe that as well. We must, therefore, value our soul even above our own life.
