Passage
For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
Galatians 5:1 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
Galatians 5:2 Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
Galatians 5:3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
Galatians 5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
Galatians 5:5 For we through the Spirit wait for the hope of righteousness by faith.
The verse centers on "testify", "again", "circumcised", "debtor", and "whole". It is saying that the verse draws attention to "testify" and "again", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "Behold I Paul say unto you that..." into verse 4's "Christ is become of no effect unto...", so "testify" and "again" belong inside that flow. In Galatians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "testify" and "again" with trust shaped by these words, not by a vague optimism outside the passage.
