Romans 3:27

“Where is boasting then? etc..] There is no room nor reason for it, either in Jews or Gentiles: not in the Jews, who were very apt to boast of their being Abraham's seed; of their circumcision; of their being Israelites; of their having and keeping the law; of God being their God; and of their knowledge of him: nor in the Gentiles, who were ready to boast of their philosophy, wisdom, and learning; of their self-sufficiency, freewill, and of the things they had in their own power.

The law of faith is that divine constitution which makes faith, not works, the condition of acceptance. Romans 3:28”
