Why do christians insist on the "Trinity" meme when it's so obvious (and, makes much more sense) that Jesus isn't God?

John 7:16 Jesus answered them and said, "My doctrine is not Mine, but His who sent Me.
John 14:24 "He who does not love Me does not keep My words; and the word which you hear is not Mine but the Father's who sent Me.
John 12:49 "For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak.
Mt 24:36 "But of that day and hour no one knows, not even the angels of heaven, but My Father only.
