How many times did Jesus use the word ‘SENT’ to denote he was not God but sent by God?

The doctrine of the Trinity teaches that all Persons mutually agree to certain roles or functions. Thus the Son mutually agreed to be sent both as a Divine Person & as a human.

The problem with the Arian or Semi-Arian belief being Non-Trinitarian is that in conclusion it leads to the belief that the Father, the Son, and the Holy Spirit are God because who you are created by is your God. The Father is the Maker of everything seen and unseen in which everything was made through the Son in which the Holy Spirit is the giver of life. So you either will come to the conclusion that there is a Holy Trinity of God (singular) in which the Divine Nature of God is undivided or you are a polytheist in which you believe there to be a Holy Trinity of Gods (plural) which of course is not supported by Scripture and is heretical to believe the Divine Nature of God is divided.

And again in Scripture the Father sends the Holy Spirit well the Hebrews believed that the Holy Spirit is the Father, so the Father sends Himself? And again why would the Father send the Holy Spirit in Jesus' name?

John 14:26

The Advocate, the holy Spirit that the Father will send in my name—he will teach you everything and remind you of all that [I] told you.
