Jesus has a relationship with God
This is but one of the many illustrations that Jesus certainly is not the Supreme Being. Jesus is God's loving servant, as also illustrated here.
This is illustrated with the word "too." While God is "always at His work", Jesus is also ("too") doing God's Work - indicated by the Greek word κἀγώ (kagō), which means "likewise" or "also" according to the lexicon.
This is called loving service.
When a person does someone else's will and works on their behalf, they have become their servant. If they freely do this work out of love, then they are that person's loving servant. This was Jesus' relationship with God.
Furthermore, when a loving servant does the work of their master, there becomes a oneness of purpose between the two. The master's will is non-different than the loving servant's will. This is the oneness (of purpose and will) that Jesus has described elsewhere: Not that God and Jesus are one and the same person.
If Jesus was God, then who is Jesus referring to when he says "My Father"? Is he making up a name and pretending there is another person, when really he is the Supreme Being? This is a ridiculous supposition.
In reality, those who accept Jesus as the Supreme Being simply do not know the Supreme Being. Sadly they have forgotten God because they don't want to do someone else's will. They want to keep doing their own will, and have Jesus' sacrifice prevent them from suffering any consequences.
Sadly, they are missing the one true relationship that Jesus was trying to show us by example and through his teachings: To love and serve our Best Friend and Protector, God. By substituting Jesus for the Supreme Being, we are ignoring the One Person that Jesus dedicated his life to.
By substituting Jesus for the Supreme Being we are also missing the relationship that will completely fulfill us.
Missing the point of Jesus' teachings
Simple observation of the activities of many sectarian institutions that claim to follow Jesus reveals that many have missed the point of Jesus' teachings.
If we are amazed that many priests in the church could possibly be so empty and deranged as to molest young children, we must know that these evils are fruits of a bad tree: That is the tree that has forgotten God.
In their pomp and ceremony regarding Jesus' blood and the focus upon having their sins forgiven, this empty philosophy has missed the very teachings that would have made them whole: A loving service relationship with the Supreme Being, our Best Friend and Protector.
This is called a higher taste. Once a person tastes love for the Supreme Being, they have tasted something that overcomes materialism and self-centeredness. Jesus illustrated this higher taste when he said:
“My food,” said Jesus, “is to do the will of Him who sent me and to finish His work." (John 4:34)
