Sorry, NO ONE is saying they have no need of forgiveness. The difference is, the true believer who is saved seeks forgiveness for their daily sin to restore an intimate relationship with God in their life, not because they lost their salvation and need to be forgiven to get it back again. Saying you lose your salvation by sinning is ultimately saying that your performance is needed for your salvation in addition to your faith - which is EXACTLY the view that Paul says is accursed because it mixes works with grace, and thus turns the gospel of grace into a false gospel.Sam Lowry said:
The two opposing views are actually these:
-By God's grace I can always find forgiveness.
-By God's grace I have no need of forgiveness.
The first is the biblical and historically Christian view. The second is the heresy of "once saved, always saved."
Ultimately, you're holding the view that "I have faith in Jesus... but I have to not sin or I lose my salvation" which is essentially the first view I described.
