I believe that we are saved by our faith in Jesus Christ.
We will never be able to stop sinning despite our best efforts, but Jesus makes up for this shortfall.
However we do have a duty to keep God's commandments - do you disagree?
I think that if a Christian flagrantly disobeys God, Jesus' sacrifice will not cover those sins:
Hebrews 10:26
"Dear friends, if we deliberately continue sinning after we have received knowledge of the truth, there is no longer any sacrifice that will cover these sins".
Are you saying that we can flagrantly willfully continue disobeying God and be forgiven regardless of how we behave?
