I don't pretend to understand all the aspects to creation, but I can explain in short how I see it. There are so many facts of scripture to consider that it's impossible to bring it all out by posting, it would require a book to even crack the surface.
I see the Trinity as three distinct persons, the Father, the Son, and the Holy Ghost, who are manifest in one God.
To make it easier to understand, I use construction terms to identify the three persons. The Owner, the Architect, and the Contractor.
The Owner is the Father, He owns everything that has been created, He spoke everything into existence.
The Architect is Christ, He is the Word from the beginning, He is the plan and design for everything that is created. He sustains everything in existence by His power and standing as the Second Adam.
The Contractor is the Holy Spirit, He brings about the actual work desired by the Father in the name of the Word.
I think it's important to see that the One we know as Christ was in the beginning the Word (the beginning as we know it, God has no beginning), the Living Word, which is shown to us in the written Word. Everything from Gen. to Rev. is revealing the Living Word to man.
The Word did not come about by creation, creation came about by the Word. Christ is the center of this universe. He is the reason for creation, therefore, He is the heir of all that the Father has made by His reconciliation of fallen man to the Father which was the plan of the Triune God from the beginning, as we know it.
This is very vague, with much scripture to be brought to light. But it is the general concept as I see it.
