Paul says something that sounds almost backwards: "The power of sin is the law" (1 Corinthians 15:56). Isn't the law supposed to hold sin back? It takes some untangling, and where the road leads is a warning about one of the most common distortions in the church today, cheap grace.
What Cheap Grace Sounds Like
Hardly anyone preaches "sin doesn't matter" outright. It's subtler. It's a quiet drift toward treating grace as a permanent cover, so ongoing, unaddressed sin becomes a nonissue because it's already forgiven anyway.
That isn't grace. It's a counterfeit using grace's name.
Real grace, Paul tells Titus, does the opposite: it "trains us to renounce ungodliness and worldly passions, and to live self controlled, upright, and godly lives in the present age" (Titus 2:12). Grace isn't there to excuse ungodliness. It's there to train us out of it.
Grace Is Power, Not Only Pardon
This is the shift that changed how I read the whole New Testament. Grace isn't only God's forgiveness for what I've done. It's also his supernatural enabling for what I can now do that I couldn't before. It's real strength to say no to things that used to run my life.
If I treat grace as a legal pardon and expect nothing to change, I've taken only half of what it was given to do.
The Phrases I've Used
I've heard cheap grace in a dozen soft sounding phrases over the years. "God knows my heart." "Nobody's perfect." "We're all just sinners saved by grace." Each one is true in a narrow sense. And each one can quietly turn into permission to stop fighting.
What I've come to see is that grace was never meant to lower the bar. It was meant to give me the power to clear it, power I never had on my own. If grace hasn't changed anything about how I actually live, then it isn't that grace is weak. It's that I've only received part of it.
