Jesus said that He came to fulfill the Scriptures ... those Scriptures being what we have as the Old Testament; thus God the Father can only be the God of Abraham, the God of Isaac and the God of Jacob.
If Christianity replaced Judaism instead of fulfilling it then we would only have the Gospels and Epistles and would lose so much insight into the nature of God.
God cannot be anyone else and we know that whether we spell the name YHWH or YHVH is immaterial, for even that isn't the true name of God because it means "I AM THAT I AM" ... which, it seems is all we need to know - for the time being.
\coming back to the original question of why do Christians have to (or choose to) accept the Jewish God ... why? Because that is WHO GOD IS, of course! Simple, huh?
Why overcomplicate with imposed convolutions what God has made smooth and straight? So much else is difficult as it is!
