God is not the name 'Jesus'. God is a Person, not an English word.
God preserves His Word in the English today (with the King James Bible). So I beg to differ.
Jesus is the second person of the Trinity or Godhead.
So Jesus is very much God. If you do not believe that truth, then you cannot post in this section of the forums.
The name of Jesus is above all names (Which would logically include even God the Father's name) (See: Philippians 2:9).
You said:
The person who doesn't know the name Jesus, but submits to the God of General Revelation, or the God revealed to Abraham (for example) via the Inward Witness DOES know Jesus (albeit not by that name).
No. That is a lie.
We are saved by believing in Jesus, and not a general revelation of God.
"Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved." (Acts of the Apostles 4:12).
"But as many as received him, to them gave he power to become the sons of God,
even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God." (John 1:12-13).
How was Paul saved?
Was it just some general revelation of God?
No.
"And the Lord said, I am Jesus whom thou persecutest"
(Acts of the Apostles 9:5).
The jailer asked Paul, and Silas,
"Sirs, what must I do to be saved?"
And they said,
"Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house." (See: Acts of the Apostles 16:30-31).
If you were there, you would say believe in the general revelation of God. So you would not be speaking the same thing Paul and Silas spoke.
You said:
It's the same Person (it's Yahweh), regardless of the name used.
Otherwise, the OT saints would be unsaved, at least those who did not know the name Jesus.
Things were different in the Old Testament. Not all OT saints had the full revelation of who their Messiah was.
