I learned this concept of the Trinity in Sunday School: sorry it is so huge! But it helps me, in my small dumb brain, to understand.
Jesus is teaching us that we can do nothing on our own, just as Jesus cannot do anything without the Father. Jesus is equal to the Father and He IS God, yet He is fully man also. He is showing the doubters, who accuse Him of preaching on the Sabbath, that His Father commands Jesus. In other words, Jesus is proving Jesus’ claims.
I must practice daily my time with the Lord, who will teach me and show me. There has to be a willingness—even an eagerness—to submit, just as Jesus submitted. Step by step I can follow His plan—be it a church ministry or ministry of doing dishes—as I submit and trust Him.
I believe Jesus sees and hears the Father through the Word and prayer.
