The Trinity being of the One and only living God is something a finite creature, which man is, cannot fully grasped or explained. It is the very being of the One everlasting and ever existing God, who is The Creator. How can we fully grasp or explain it ? However, the scriptures are abundantly clear that God has revealed Himself as such. To worship God in spirit and truth, in exercising our biblical faith, we need to know God as fully as He has chosen to reveal Himself, our reliance must be based on His written Word.
What do we mean when we say the Bible declare that God is incomprehensible? When the Bible states that God is incomprehensible, we mean God through scripture is saying that there is much about Him that is still mysterious. God is simply beyond our understanding and comprehension. Augustine of Hippo was trying and struggling hard to understand the Trinity nature of God without success until he recognized the humbling fact that as a finite creature he was merely trying “to cram the ocean of God’s truth about Himself into his little box of brains”.
“There is nothing that the Father is that the Son is not, except that the Son is not the Father.” * Quote from Notes on Hebrews 1:1-4 by David Linden
There is nothing that the Father is and the Son is that the Holy Spirit is not, except that the Holy Spirit is not the Father and the Holy Spirit is not the Son.
And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; and behold, a voice from heaven said, “This is my beloved Son, with whom I am well pleased.” Mat 3:16-17
The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all. 2 Cor 13:14
In the unity of the Godhead there be three Persons of one substance, power, and eternity: God the Father, God the Son, and God the Holy Ghost. The Father is of none, neither begotten nor proceeding; the Son is eternally begotten of the Father; the Holy Ghost eternally proceeding from the Father and the Son.
