Paul, after demonstrating that religious people are just as sinful as the lost world, answers the question, “What advantage do we have?”

Basically, “If my religion hasn’t earned me any favor with God, what was the point to that?”

Paul answers the question by stating that our advantage was that we were entrusted with the word of God, the Bible. Then, in a theological eloquence that could only be inspired by God Himself, demonstrated God’s grace and salvation of us, in spite of our sinfulness.
