Chapter 4: The Biblical Revelation of the Triune God and the identity of Jesus Christ
The belief that Jesus Christ is the Eternal Son of God is based on the belief in a Triune God.
The belief in a Triune God is not a Christian invention, but is a Biblical doctrine.
Let me ask you this question: "From where did we get our knowledge about God?"
From one of two sources:
From our foolish hearts and darkened minds, which is what the pagans did, and this is what the apostle Paul recorded concerning the pagans:
Because that, when they knew God, they glorified Him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, and changed the glory of the incorruptible God into an image made like corruptible man, and to birds, and four-footed beasts, and creeping things... who changed the truth of God into a lie, and worshipped and served the creature more than the creator, Who is blessed forever, Amen (Romans 1:21-25).
Or we know the true God by a special revelation from Him, which we Christians have received in the Bible.
We take God at His word and believe His revelation of Himself.
God is everlasting, having no beginning; therefore He must be self-existent and self-sufficient.
No one can fully comprehend God. The finite human mind cannot contain the infinite God. If we could contain God in our minds, He would no longer be God.
There are many important questions concerning God that need an answer such as:
Before God created angels and men, with whom was he talking?
Before God created angels and men, whom did He love, since we read in I John 4:16 that "God is Love." And in the Quran we read: "Lo! my Lord is Merciful, Loving" (Surat Hud 11:90).
Before God created angels and men, whom did he see, and whom did he hear?
If God’s attributes were not functioning without His creation, then He is incomplete in Himself, being completed by His creation. This is a heresy.
All the former questions concerning God have a satisfactory answer in the belief of a Triune God.
