Jesus could “only do” what he saw his Father doing – this does not mean he had no will of his own, but that his will was in submission to God’s will. He considered his “own” thoughts to be inconsequential, he was only concerned with his Father’s thoughts. “He considered equality with God not a thing to be grasped”.
So too, are our thoughts to be “taken captive to Christ”. And He will, as the Spirit, mediate them before God. In this way, we are “participants in the divine nature”, doing the divine will. For, because of this mediation, he says that we are able to do greater things than he himself did.
This seems incredible, but taken at face value, it means we at the very least have the potential to tap into Him who sits at the right hand of God himself. That our heart is capable of being cleansed to such an extent that we, like Him, may see ourselves as only a vessel, a “temple” of His Spirit, to be obeyed at all times. Somewhere in this, “Mountains can be moved”.
[James 4-8 “purify your hearts”] [this is the work of God, that you believe in the one he sent]
