Good question. Let’s look at the facts: The Savior promised by God all through the Old Testament was going to be His Son. “You are my Son, today I have begotten You.” (Psalm 2:7) . So what we’re asking is: could God have fathered more than one Son?
We know the answer to this question from one simple phrase: Jesus is called the “only begotten Son of God”. (John 1:14) There are no other begotten sons of God. Jesus is and always will be the only Son who was physically fathered by God.
One Savior/Messiah/Son of God was promised all through the Old Testament. Only One.
If there had been or could be other begotten Sons of God, then there would be many Saviors. But there was only One.
What are the implications of this, then?
- That means Jesus is the only way to salvation. There is no salvation in any other person, or in any other name. John 14:6, Jesus said, “I am the way, the truth and the life. No man comes to the Father except through Me.”
- And it means if anyone else ever comes along saying they are the Savior of the world, run very fast in the other direction. “Nor is there salvation in any other, for there is no other name under heaven given among men by which we may be saved.” Acts 4:12
