Actual, the Scriptures say the Godhead is a mystery.
What we can know by revelation is :
- General revelation by Creation read Romans chapter 1
- Special revelation The word of God
- Illumination from the relationship with the Lord Jesus Christ and the Holy Spirit.
because we are limited and God is not limited, we are unable to fully know about the Divine NATURE OF GOD.
We from His creation and word and salvation receive enough for righteous living and appropriate worship.
TO sat we can know all is very much untrue.
