With freedom from sin comes personal responsibility. Believers have the personal ability to respond to God’s grace rather than continue to live in sin. Response ability.

Under the New Covenant, we are free from sin. We are free from sin in that God is no longer holding our sins against us.

Paul explains in Romans 6 that freedom from sin doesn’t give one an excuse to continue in sin; it’s just the opposite. It’s the opposite because we are under grace.

If you have a traditional understanding of grace, you will not grasp the power of “under grace.” Grace is traditionally defined as unmerited favor. It’s equated to mercy. The sentiment is that God shows you grace even though you deserve punishment. That’s incorrect. Grace and mercy are different. Mercy is undeserved forgiveness, but grace is inner strength.
