TSK · Galatians 5:4

Now to him who works, the reward is not counted as grace, but as something owed.

For being ignorant of God's righteousness, and seeking to establish their own righteousness, they didn't subject themselves to the righteousness of God.

I marvel that you are so quickly deserting him who called you in the grace of Christ to a different "good news";

Behold, I, Paul, tell you that if you receive circumcision, Christ will profit you nothing.

But the righteous will live by faith. If he shrinks back, my soul has no pleasure in him."

For if, after they have escaped the defilement of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in it and overcome, the last state has become worse for them than the first.

Remember therefore from where you have fallen, and repent and do the first works; or else I am coming to you swiftly, and will move your lampstand out of its place, unless you repent.
