Some of us are better at sharing than others. Starting when we’re little, we usually have to be taught to share because selfishness seems to be innate.
One thing we know about Jesus is that he’s good at sharing. God’s plan, from before the foundation of the world, was to share himself with us by becoming one of us. We know how he did this – emptied himself of his omniscience, omnipresence and omnipotence (Kenosis of God: The Self-Limitation of God – Father, Son and Holy Spirit, David T. Williams) to become a human being, while still being God. He retained his love and holiness while humbling himself in submission to both his Father and to humanity.
He continues to share himself with us by sharing his faith, obedience, love and humility. We have very little of any of these and I know from experience that we can’t attain faith, obedience or any other godly attribute on our own or by our own effort. It doesn’t work. We have to trust God to impart these things to us by sharing his power and who he is with us. God continues to be kenotic in both his self-emptying and his munificence to us.
