I do not entertain the Modalism doctrines that the Father, Son, and the Holy Spirit are not three distinct individuals at all. I also do not believe as some do that the three personages of YHWH are just different manifestations of God.
They are ONE in Holiness, purpose, and deity. They are the Father, The Son, and the Holy Spirit; that Spirit of God, and God of peace by definition. In total agreement God the Father sent Jesus, Jesus did always those things that pleased the Father even going to the cross, and the Holy Spirit raised Jesus from the dead and works in us to separate us unto the full purpose and will of God we know as sanctification.
What benefit to God? He loved us. He is taking out of His people a bride for His Son, and He will have us with Him for eternity He paid so dearly for. A good example or type of what God is doing in this age is the story of Abraham (Father), Eliezer (Holy Spirit), Rebekah (Bride), and Isaac (Jesus) in Genesis Chapter 24.
Gen 1:26 And God said, Let us make man in our image (Jesus), after our likeness:
My thoughts. Blessings inn Christ Jesus.
Amen brother. Being around pentecostal folks, I use to say that Jesus is the Word of God!!!! in my mind, He was God, but the Word part of God. If I really think back and was honest with myself, I actually believed Jesus was like a 1/3 part of God, being the Word part, the Holy Spirit being the power end and the Father like the creator part.
I believed they were separate, but it was more of a modelist point of view. Leaning toward the 1 becomes 3 and not the 3 are as one. I was just following everyone else.
We follow things without comparing scriptures, praying about it and seeking what's right ourselves. I wish we all were not like that, but we are if we are not constantly on guard and willing to learn and change.
I was thanking God for something He did for me, then I thanked Jesus, but then said, "No, Jesus your God also, so I thank you." I had really just lumped them all into one, but was really being thankful.
Then I heard a voice, not with my ears, but inside, and for some reason I knew it was not the Father. It was very strange but He said........... "
I Am, I am Not my Father." It was straight forward and very loud and matter of fact. Like a correction. It took several years to sort it out as the doctrine was just that deep.
As you said, Jesus here before the foundation of the World with the Father, the Father saying to him. Let us make man in our image. All things the Father made were for him (By Greek Word dia, meaning through or because of something) That the Son would have all preeminence of all things predestined before the World was made, the Father giving Glory to the Son, restored back as the Son came and was faithful in all things and without sin having the bondage of flesh by which he rightfully could call us brothers and sisters.
Joh 17:5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was.
There is One Lord God, the Father of all things the Savior whom sent his son by whom all things consisted.
For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness,
and denying the only Lord God, and
our Lord Jesus Christ.
(Jud 1:4)
Remember the former things of old: for I am God, and there is none else;
I am God, and there is none like me,
(Isa 46:9)
Isa 42:5 Thus saith
God the LORD,
he that created the heavens, and stretched them out; he that spread forth the earth, and that which cometh out of it; he that giveth breath unto the people upon it, and spirit to them that walk therein:
Isa 45:5 I am the LORD, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:
But to us there is but
one God, the Father,
of whom are all things, and we in him; and
one Lord Jesus Christ,
by whom are all things, and we by him.
(1Co 8:6)
There is One God the father of whom all things became and One Lord Jesus Christ by (Through and because of) are all things and we by Him.
That is TWO!!!! The Son as one with the Father and we in the Son as one, with them.
Oneness, versions of the Trinity, and modelism attempt to make the Son just as part of the Same God system, but the Son is Lord of Lords, King of Kings, the one true God and given all things, and all things put under his feet. It's the spirit of the antichrist who has tried to erase and diminish God the Father actually having a real son whom he honored and exalted. One reason I am not a big fan of these Trinity, Modelist, and oneness doctrines.
The Original Trinity doctrine has Jesus begotten before the foundation of the World. (325ad) He was only begotten by the spoken word as human, and has no creation date, but always has been with the Father.
blessings.
