I had a long, long think about this, and here are my thoughts;
Examples OT; Exodus 34:14 says, “For you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God”
Examples NT: Matthew 15:25 Then she came and worshiped Him (Jesus), saying, "Lord, help me!" -
Throughout the bible it tells of God being 'one', and being unchanging, but his Spirit being in all of us, including Jesus.
Ephesians 4:6 One God and Father of all, who is above all, and through all, AND IN YOU ALL.
Deuteronomy 6:4 Hear, O Israel: The LORD our God is ONE LORD:
Isaiah 43:11 I, even I, am the LORD; AND BESIDE ME THERE IS NO SAVIOR.
Malachi 3:6 For I am the LORD, I CHANGE NOT; therefore ye sons of Jacob are not consumed.
Isaiah 45:6 That they may know from the rising of the sun, and from the west, that there is none beside me. I am the LORD, and there is none else.
Then it also says of God's word being done in flesh, albeit in John.
John 1:1 'In the beginning was the Word, and the Word was with God, and the Word was God.' 14. And the Word was made flesh.'
A lot of people take this as proof of Jesus being God. But I beg to differ. Now here, the word, to me, is all that God stands for.The word is His teaching, his will, and his grace. It is his way of thinking. It is his wisdom, and his love. And Jesus inherited all of that. As did we to a certain extent.
Jesus also says that He and God are one. That is where it get's confusing. If God is the only God, and he is one God, and is unchanging, then how can Jesus also be God? Well, the simple, indisputable answer is, he cannot.
I look at this scripture, and at Jesus, not as being PHYSICALLY God, but as having God's spirit, God's will, and God's desire and knowledge and wisdom in him. The same way our fathers try to pass their knowledge and wisdom and way of thinking, and belief, onto us. To me, when Jesus says 'The Lord and I are one', I always took it in the context that this was a metaphor for their singular way of thinking and their shared divine power.
Jesus was born of a human mother, and had a divine Father. He was flesh and blood, as is man, but had also part of God in Him, (the same way in which you and I have parts of our biological Father's in us). Now we know that God cannot be impure. He is perfect. Therefore, how can he have flesh and temptation, and fear, and anger? The simple indisputable answer is, he cannot.
There are many lines in scripture that show us that Jesus and God, although they share many things with each other, are separate physical entities.
For instance, when God speaks of Jesus 'sitting at his right hand', this implies that they are to be 'together in Heaven', but are as separate beings, albeit sharing the same power and knowledge. Also when Jesus speaks to God and prays to God, he does so as a separate entity, for instance, in the olive trees before his capture. When he cries out to God on the cross, he does so as a separate entity. 'Oh Father, why have you forsaken me?'
God and Jesus, and us all, have the Holy Spirit in us, but we, and Jesus, are OF God. We contain the Holy Spirit. As does Jesus. As do the angels!
'And God breathed his Holy Spirit into the dust, and there was life'
BUT, Jesus had our temptations, and our fears, our anger. He, physically, was a human. But with the divine will to resist such temptation. For instance, in his 40 days in the desert, he resisted. But if he WAS God, he would not even have such temptations in the first place. God is not tempted by worldly things. Nor by Satan.
Colossians 2:9 'For in Him all the fullness of Deity dwells in BODILY FORM,' - Jesus has God's will, and some of his power, the ability to heal for instance, but he IS also a man.
You see, Jesus is a man in Heaven, sitting at God's right hand. And he was a man on Earth. But as the scripture shows above, the fullness of God dwelt in Him. He has God's wisdom, His power, His love, His knowledge, His hope, His faith. Jesus came back as a man, with holes still in his hands. Then he went to sit at God's right hand. Jesus had human mother, human cousins. Shared blood with human beings.
Therefore the trinity must not be God in full, for all the reasons above, but I think it is this;
God is the Father, whom we worship. He is the ONE, SINGULAR God.
Jesus is the Son, whom we pray in, and whose example we follow. He is OF God. God's human Son, who inherited God's wisdom and Truth. And spread his wisdom across the world. He is who died for HUMAN sin, and only a human could potentially commit, and take the blame for, such sin. But only with part of God in him, could he handle such sin, could he take the pain, could he have such resolve. Only with part of God in Him that makes him so sure and so faithful, and so never endingly believing. He was God's Son, and he knew beyond any doubt that God's plan was true and was the only way. A lesser man could not have known such things, or would have had doubt. But not a man with so much God in him.
And the Holy Spirit is God's love, God's will, and God's grace, which is in all of us, somewhere.
We all came from God - Everything did. But we are not all God.
It is not hard to believe, with all God's power, that he could make himself into three, but it IS hard to believe, that God, with all his promises and none of them ever broken, that he would tell us, specifically, that he is ONE GOD AND DOES NOT CHANGE, then split into three. NO. In the Jewish book, which the people of Jesus time, and in fact, Jesus Himself, would have taught from, it states that GOD is one God, only one God, and does not change. Now if that's what Jesus was teaching, and that's what Jews knew at that time, then that is what God MUST be. The trinity is not God as a whole, GOD, THE FATHER, is God as a whole. The trinity is really just three separate things; God being Lord, Jesus being his Son, and the Holy Spirit being God's power, his knowledge, his spirit; everything he stands for. Imagine God's spirit floating around, touching people. It is to me, the means by which he shows his power. Like a force.
Read the scripture back and tell me it does not all make sense that way.
The bible is full of metaphor and ways of speaking that are not meant to be taken literally. When Jesus says that God and Him are one, this must be a metaphor for the way that Jesus has (pardon the expression) partly divine 'DNA' ( I can't think of a better way to put it), and has God's knowledge and powers. It has to be.
