Andrew Farley, The Naked Gospel:

Grace is the system that the Holy Spirit uses to counsel and teach us on a daily basis. Grace is in place, whether or not we've sinned recently. We worry that an absence of law will result in a lifestyle that is out of control. This concern is natural. But is contradicts what the Scriptures say about the effects of grace. grace isn't just a treatment for sin; it's actually the cure for sin!

When we question the function of grace in our lives, we're insulting God's intelligence. Would he users in a New Covenant that not only allows but actually promotes sin? Is God foolish to think that grace really motivates us to live godly lives?

The secret is that grace deactivates our pride. Removing the law from our lives means our self-effort is no longer prodded to control behavior. The law excites human effort. It encourages us to depend on resources outside of Christ. But unconditional acceptance deactivates human effort and allows the Holy Spirit to be all that he wants to be through us.

Our greatest fear is that we'll be out of control. But we were never made to be in control. Self-control has always been a natural attribute of the Holy Spirit. The reason he lives within us is to produce the self-control that we're afraid we'll lack under grace.
