Malachi 2:10 10
Have we not all one Father? Has not one God created us? Jer.3:19 ‘You shall call Me, “My Father,” Jesus said  “Our Father who art in Heaven”
And not turn away from Me. (singular) Deut.32:6 Do you thus deal[a] with the Lord,
O foolish and unwise people?Is He not your Father, who bought you?Has He not made you and established you?

Gen.1:1 In the beginning Elohim created the Heaven and thee Earth. If we miss understand this verse the rest of the bible is built on sand! Upon this Rock I shall build my Church Matt. 16:18 15 He said to them, “But who do you say that I am?”
16 Simon Peter answered and said, “You are the Christ, the Son of the living God.”
17 Jesus answered and said to him, “Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven. 18 And I also say to you that you are Peter, and on this rock I will build My church, The very foundation of the Church of His Father is founded on Christ witness that he is the very son of the One God of Israel. Matt.4:10  Then Jesus said to him, [b]“Away with you, Satan! For it is written, ‘You shall worship the Lord your God, and Him only you shall serve.’ ”

Luke 2:52  And Jesus increased in wisdom and stature, and in favor with God and men. As the boy Jesus grew into manhood he increased in Favor! With Who? God. How could he grow in favor and knowledge if he was God, he would already posses it. The man Jesus had the same growth as all humans he grew up applied himself made something of himself and not to under mind that, His father was God Himself.

Jesus understood who the God of the old testament was and at 12 he understood that the God that his mother and father  and the rest of the people of Israel worshipped was none other than His father. We must remember that during Jesus 33 years he was going to the temple worshiping and making offerings to the only God he knew of Israel! The new testament wasn’t written till years after Jesus death and resurrection. The only God being worshipped during that time, was the only God they new, the father. Jesus being elevated to god status took a couple of century’s and not confirmed till Nicea 325. By then the legend of the man Christ took on a legend of its own and the Three god concept came as the church got further and further off track from the monotheistic God of the bible, confirmed by Jesus himself in many text including Mark 10:6 and others. Understanding that only the father is God and he acted alone is the foundation of Who Is and Who isn’t God…
