Thematic Bible: Liberty being threatened by legalism

Stand fast therefore in the liberty with which Christ has made us free, and be not entangled again with the yoke of bondage. Behold, I Paul say unto you, that if you be circumcised, Christ shall profit you nothing. For I testify again to every man that is circumcised, that he is a debtor to do the whole law. read more.
Christ is become of no effect unto you, whosoever of you are justified by the law; you are fallen from grace. For we through the Spirit wait for the hope of righteousness by faith. For in Jesus Christ neither circumcision avails anything, nor uncircumcision; but faith which works by love. You did run well; who did hinder you that you should not obey the truth? This persuasion comes not of him that calls you. A little leaven leavens the whole lump. I have confidence in you through the Lord, that you will not be otherwise minded: but he that troubles you shall bear his judgment, whosoever he be. And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offense of the cross ceased. I would they were even cut off who trouble you. For, brethren, you have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
