Question: Why does God demand absolute loyalty from our souls?
Answer: Darkness can’t coexist with love and light. God won’t let you choose a part of your life that you can set apart for him and then keep on doing what you want, i.e. sinning, with the rest of your life. We must give up all our heart to God because He deserves it. He gave up his entire life as a human for our sake. He feeds us with His Body and Blood; His love is absolute; He came into this world to save us. That is why He cannot say that there is a part of your heart and your life that belongs only to you and that you can dispose of as you please. You have to hand your whole life over to God and to rely on his Providence. That is how we can enter eternal life and defeat death. Ye cannot serve God and mammon (Cf. Matthew 6: 24). You can’t divide your heart and your life. You’ve got to choose yes or no. If we decide to follow Christ, we must follow him till the end. But he that shall endure unto the end, the same shall be saved (Matthew 24: 13).
