Not quite the phrase needed here, a a 'fall for grace' comes from here:
Galatians 5
1. It is for freedom that Christ has set us free. Stand firm, then, and do not let yourselves be burdened again by a yoke of slavery.
2. Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all.
3. Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law.
4. You who are trying to be justified by law have been alienated from Christ; you have fallen away from grace.
Haggard merely (?) sinned; he has NOT tried to justify getting into Heaven by following the LAW.
Sorry, I really do not understand what you are trying to say???
