For I say through the grace that is giuen vnto me, to euery one that is among you, that no man presume to vnderstande aboue that which is meete to vnderstand, but that he vnderstande according to sobrietie, as God hath dealt to euery man the measure of faith.
Romans 12:1 I Beseech you therefore brethren, by the mercies of God, that yee giue vp your bodies a liuing sacrifice, holy, acceptable vnto God, which is your reasonable seruing of God.
Romans 12:2 And fashion not your selues like vnto this worlde, but bee yee changed by the renewing of your minde, that ye may prooue what that good, and acceptable and perfect will of God is.
Romans 12:3 For I say through the grace that is giuen vnto me, to euery one that is among you, that no man presume to vnderstande aboue that which is meete to vnderstand, but that he vnderstande according to sobrietie, as God hath dealt to euery man the measure of faith.
Romans 12:4 For as wee haue many members in one body, and all members haue not one office,
Romans 12:5 So we being many are one body in Christ, and euery one, one anothers members.
The verse centers on "grace", "faith", "through", "giuen", "vnto", "euery", "presume", and "vnderstande". 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 2's "And fashion not your selues like vnto..." into verse 4's "For as wee haue many members 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.
