Today I could not get away from the contrast of the b pairs. First, Mat 16:17-19: On the rock of the revelation of who is the Son of Man, Jesus will build His ekklesia. When the ekklesia knows who Jesus is, the gates of Hell will not be able to withstand them. By faith in that name, the ekklesia will be given keys of the kingdom of heaven. Keys open gates. Hmmm. Those things that the ekklesia binds on earth will be bound in heaven, and those things that the ekklesia looses on earth will be loosed in heaven.
Now, the 2b pair, Mat 17:14-21, is the contrast to that. A boy tormented by a strong demon is brought to the disciples, while Jesus is up on the mountain being transfigured. These are the nine disciples who did not go up with Him. They are unable to cast it out, even though Jesus had previously given them authority over demons, to cast them out. The gates of Hell are prevailing against the disciples.
Jesus revealed to them that they could not cast it out because of their unbelief. They did not have faith in His name, in who He is. If they did have faith, whatever they bound on earth would be bound in heaven, and whatever they loosed on earth would be loosed in heaven. If they did have faith, they could move mountains from here to there, and nothing would be impossible for them.
Why is knowing who Jesus is so important? Because the authority is not in me. I do not have authority to cast out demons or move mountains. The authority is in Jesus, because of who He is. He is the Son of the Living God. When I am a man who is also under authority, then I can say to my servant, Do this, and he does it, and Come here, and he comes, and Go there, and he goes (Mat 8:5-13). They are not obeying me — they are obeying the authority behind me. When I know that, that gives me faith, that what I say will be obeyed, whether by demons or by mountains.
