Can we bear fruit without being personally transformed? Yes, if we’re willing to settle for a skimpy crop. But we won’t be successful in producing what Jesus wants—“much fruit.” God wants to see us radically changed. And since we know we can’t transform ourselves, He must have a method to bring it about. God has His part in the process, and we’ve got ours.
If transformation is ever to happen, we must cooperate with God as He goes about working in our life. For us, it’s all about choice! But we often have to come to the end of ourselves—finally fed up with failure—before we are able to make that commitment. You may be at that point in your life right now! If so, unconditionally give yourself over to God, and then take action by walking in obedience. Remember, this is a choice we make day by day.
