In Tim Keller's excellent expository guide to Galatians says there are four kinds of people concerning works & the law. I'll give you his categories with a very short explanation. Check out Galatians For You (Amazon, Kindle, WTS) starting on page 117 for a fuller explanation.
- Law-obeying, law-relying | "Under the law," often smug, self-righteous, superior. Sensitive to criticism despite outward confidence. "Pharisees." They go to church.
- Law-disobeying, law-relying | Strong works-righteousness, but not living consistently. May go to church, but on periphery b/c of low spiritual self-esteem. Guilt-ridden.
- Law-disobeying, not law-relying | Secular & relativistic. Vague spirituality. Choose own moral standards & insist they are meeting them. Earn salvation by feeling superior to others.
- Law-obeying, not law-relying | Understand the Gospel and living out the freedom of it. More tolerant than #3, more confident than #2, more sympathetic than #1. Still struggle to live out #4 and see the world as a #1, #2, or #3.
