What is the purpose of God (the father) if Jesus created everything; died for our sins; will be the judge on Judgment Day; and will rule afterwards?

It is claimed that Jesus, Father, Holy Spirit are equals and each is God in their own right. But God (the father) gives orders to the other two and they DO HIS WILL. Nevertheless, Christianity seems to emphasise Jesus as the Key "person" in the "Godhead" in view of the roles he has. IS GOD THE FATHER RETIRED? WHAT IS HIS ROLE IN THE GENERAL SCHEME of things?
