I am still reading Romans.

For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the measure of faith God has given you. Romans 12:3

So this means that we should rate ourselves with faith not works in sober (Serious) Judgment.
Most of Romans is talking about this. The good things that come by our faith. I am going to try to find a verse in every chapter of Romans about this in 3 days total. I am typing all this not copying.

Through him and for his name's sake, we received grace and apostleship to call people from among all the Gentiles to the obedience that comes from faith. Romans 1
obedience that comes by faith.

Chapter 2 talked about Obeying the Law outwardly but not inwardly.

This righteousness from God comes through faith in Jesus Christ to all who believe. Romans 3

"Abraham believed God, and it was credited to him as righteousness." Romans 4
