"We can only trust and assume that the OT accurately portrays God."<quoted text>The bible is about the God of Israel, and that God does not change. Malachi 3:6 "For I am the Lord, I change not; therefore ye sons of Jacob are not consumed". We can only trust and assume that the OT accurately portrays God. It's the only record we have and it will be used to prove the coming redeemer is the God of the Jews. The nation of Israel was created for this reason, for God to become the King of the universe.
And if it doesn't?
Where will you go from there?
If you conclude that the Bible is suspect, will you go on a murderous rampage?
