How do you know that all the people who were believers in Galatia who received Paul’s admonishing epistle, did not all hear Paul and reject and turn away the judaizer heresy
After all, we know that John said “those who know God hear us”. (Apostolic teaching as the Word of God, not of man)
Galatians 5
1
Stand fast therefore in the liberty by which Christ has made us free,
and do not be entangled again with a yoke of bondage. 2 Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing. 3 And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law. 4
You have become estranged from Christ, you who
attempt to be justified by law;
you have fallen from grace. 5 For we through the Spirit eagerly wait for the hope of righteousness by faith.
verse 1- Christ has made those Paul is addressing free. They have liberty. They are told to stand fast in it.
Established fact.
verse 1 - A Warning, not to be entangled AGAIN. Which means they were previously entangled, became untangled, and are now at risk of become ENTANGLED AGAIN.
verse 2 - By Gentiles now going to follow Jewish laws by becoming Circumcised, it shows they are trying to follow a Law to be Right with God. They are not right by the outward act to prove their righteousness. They are right only by Faith in Christ who is our righteousness.
verse 3 - if you want to follow the law to obtain righteousness then you are under the obligation to uphold the entire law which is impossible without Christ.
verse 4 - Justification is by Christ alone. Therefore a WARNING. These being addressed can become ESTRANGED FROM CHRIST.
Tell me how do you become estranged from Christ if you were never in Christ?
verse 4 - You have fallen from grace.
How can you fall from grace if you never received grace? Or put another way, how can an unbeliever fall from grace if they were never in grace? Only a believer can fall from grace. That is what it is saying here. And if it a believer falling from grace then a believer can lose salvation through unbelief, because it is grace that saves.
