Here's one of the key verses that led me out of the trap I was in many years ago:
Having begun by the Spirit, are you now being perfected by the flesh?
Gal 3:3b
"Flesh" is a reference to unregenerate, weak, human nature. Trying to achieve righteousness by works (such as circumcision - and a WHOLE HOST of such works that people on this thread believe will make the difference for them) or, life in the flesh.
You read what Paul had to say, I have no doubt you have also read what Jesus had to say, if yo love me you will keep my commandments.
Boasting about faith is no different than boasting about works,
Let’s see some of it.
