If you really had a true sense of your "completeness in Christ" the philosophy of mortal man couldn't spoil and rob you of anything. Jesus gave us a science of Spirit to discover and prove. It begins with discovering divine Love and branches out from there. Most churches don't teach this vital truth. But if you were sitting at the feet of the Master back then you would both feel and know that this is true. Far from focusing attention on himself, he turned the thoughts of his students to the heavenly One, as an inspired Jewish Teacher would. But the Master took it way beyond what the Jews believed when he proved his mastery over matter so marvelously and then told his followers that if they really did reform their consciousness and understand his teachings and example that they could demonstrate their power in God even as he did and with greater works. This is the real "completeness in Christ" that most have yet to discover yet is within our reach here and now.
