The writer of Romans is at least wrestling with the "how-to's" of salvation -- what it means to be made right with God. On this subject, the human side of the writer wants to keep saying, 'It all depends on how well I do in the sight of God'. And the divine guidance in my own words to the human writer keeps on encouraging this thought -- 'You are not loved by God based on your works no matter how good they may be, but rather you are loved by God only because God wants to love you (even if it is in spite of yourself).'
Verses that stuck out to me were as follows. As a background to them, Abraham has always been seen as the father of Israel kind of like George Washington is seen as the father of the United States.
The aim of the Judeo-Christian life is to be made righteous/holy/good/upright/godly/right by God. But it can only be a work by God on me and God's work on me enables me to work for God. Sounds so odd, but for all that is just the way it is.
