This is actually a HUGE statement. To love God with ALL your heart, soul and might. It is easy to kind of love Him. To devote part of your life to Him. To let Him control part of your doings and thoughts. But to give Him ALL, to fully surrender to His power in and over your life, that is hard. As humans, worrying and wanting to control our circumstances, wanting things to go the way we think they should, is somewhat normal. But it is not what God wants, not what He originally intended at all. He wants us to truly surrender to Him, serve Him, love Him–and to do that we need to surrender our lives to others, serve other people, and love them–even our enemies. For in doing that we love Him. We are called to love Jesus this way because it is only right to love Him as much as He loves us. It is only right to equal the gift He gives us–which we can never fully do, but only hope to begin.
