Is the Book of Romans a Measuring of Faith?

The book of Romans is the most logically organized, I believe document that has been written by human hands under the inspiration of the Holy Spirit. That's my opinion. Maybe you could argue for something else, but Romans is a masterpiece. When he brings forward the example of Abraham, exhibit A, exhibit Abraham for faith, he says he didn't waver in his faith. But watch this when he was a hundred still waiting for a son. He got so impatient his wife was like, sleep with my maid and she'll give us a son. And maybe that'll be close enough. Have you ever tried to follow God close enough?
