Lead a group of men in my church through this book. A lot of them found the initial chapters a bit more difficult to weigh through. I would agree that part 1 felt more polemical, and could feel a bit more technical or abstract for those less familiar with this sort of writing or subject matter. However, part 2 seems to take a shift in tone. In these latter chapters especially, one of the things I appreciated about this book was the doxological tone and orientation naturally woven throughout. As I read, I found myself experiencing gratitude to God and standing in awe of Christ. I believe this book originally came out of a series of lectures Murray delivered (?). And it certainly reads like that. It feels a bit different in that way from other systematic treatments of soteriology. Very insightful and well done.
Ephesians 2:8 states that one is saved by grace through faith. Now, this is a relatively well known verse. And the concept of salvation by means of faith in Christ and His saving work alone is also relatively well known, at least among evangelicalism.
Maybe your familiar with this truth. I hope you are. But have you ever thought to yourself, “why faith? Why is it that faith saves as opposed to something else like good deeds, joy, sorrow, gladness, or a sense of surreal peace?” Obviously it was God who determined faith to be the means of man’s salvation; it’s not as if this was some external law or obligation that was imposed on Him. So, why faith? Why is God’s plan of saving people by His grace through faith. Why does He count those with faith as righteous (Rom 4:3; cf. Gen 15:6)?
