How do I know that Christ is true God? My answer: the Spirit of truth reveals it to me. It sounds as if I am trying to avoid an argument, but I am telling you as straight as I can. Truth is never complicated nor roundabout. It's always blunt and never slippery. It cannot be scientifically proven. If you have to explain a truth, it cannot be one. Truth always challenges us to accept it or reject it, so faith is required. And you must discover it on your own.
