Which commandments? The Law of Moses or the NT? I don't know of anyone who obeys the Law. Galatians is clearly explaining that we are not under the Law, period. We have the New Covenant that Jesus shed His Blood for.Do you really think Paul would object and criticize me for obeying God commandments? Do you think my obedience is not bearing fruit for God? If obedience isn't a fruit or result of God's doing, where does it come from, knowing we can't do it of our own selves?
Galatians 5:1-4 (NKJV)
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.
