Passage
But having different gifts, according to the grace which has been given to us, whether [it be] prophecy, [let us prophesy] according to the proportion of faith;
But having different gifts, according to the grace which has been given to us, whether [it be] prophecy, [let us prophesy] according to the proportion of faith;
Romans 12:4 For, as in one body we have many members, but all the members have not the same office;
Romans 12:5 thus we, [being] many, are one body in Christ, and each one members one of the other.
Romans 12:6 But having different gifts, according to the grace which has been given to us, whether [it be] prophecy, [let us prophesy] according to the proportion of faith;
Romans 12:7 or service, [let us occupy ourselves] in service; or he that teaches, in teaching;
Romans 12:8 or he that exhorts, in exhortation; he that gives, in simplicity; he that leads, with diligence; he that shews mercy, with cheerfulness.
The verse centers on "grace", "faith", "having", "different", "gifts", "been", "given", and "whether". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The nearby context moves from verse 5's "thus we being many are one body..." into verse 7's "or service let us occupy ourselves in...", so "grace" and "faith" belong inside that flow. In Romans context, the local focus is righteousness by faith, union with Christ, life in the Spirit, and God's covenant faithfulness.
A plain takeaway is to answer the verse's own emphasis on "grace" and "faith" with trust shaped by these words, not by a vague optimism outside the passage.
