In order for me to be forgiven I must truly believe that Christ is the son of God and shed His blood for me. How can I believe that Christ gave up being God, was beaten and killed so His blood could be sprinkled for me, then not show my love by obeying His commands? If He is what He says He is, and He did this for me, how can I not totally submit?
Extra Credit: First we are saved, then we obey. Not because we have to, but because we want to. Without the desire to obey I submit there is no true faith. Faith prompts us to obey.
