The new osas can not produce the genuine joy and peace of God, only a fleshly counterfeit:
"
9Whatever you have learned or received or heard from me, or seen in me—
put it into practice. And the God of peace will be with you." - Philippians 4:9
Nowadays, the new style osas church calls that 'works salvation'. And that you get the peace of God even if you don't ever put the Lord's teachings into practice, and that you lose it by trying to put the Lord's teachings into practice. Why did Paul even waste the ink in the verse above if that was true? Obviously, peace and joy come from obedience, not from a fake gospel that says you have the grace of God when you live outside of the grace of God.
