“Much in every way. To begin with , the Jews were entrusted with the oracles of God.”
Paul is now answering the “advantage” question of verse 1. What advantage does a Jew have in trying to earn salvation?
Paul does list one very significant advantage a Jew would have over a Gentile concerning salvation: the oracles of God. They are the Old Testament Scriptures, given by God to Israel. There are verses throughout the Old Testament giving promises on how God was going to save Israel.
That is an advantage over the Gentiles of the day in trying to see and understand salvation.
We have these oracles plus the New Testament. It’s another reason why people today are without excuse in salvation. Ignorance of God’s truth is not an excuse before him one day. His Word is here and available.
