Many holiness-minded individuals fear the doctrine of grace by faith because they think it leads to antinomianism. I have no doubt that some have used grace as a pretext for sin, but they do so without the support of Scripture. Scripture is clear that the grace that saves is the same grace that teaches us to deny ungodliness (Titus 2:12), and empowers us for holiness (Romans 6:14). To calm the minds of grace-fearers, and to correct the minds of grace-abusers, let me offer the following medical analogy.

Sin is like a cancer. It destroys the good cells in our body, and eventually leads to death. To treat this deadly disease one must undergo chemotherapy (grace). But would anyone in their right mind willingly inject their body with cancerous cells simply because a treatment for the ensuing cancer is available? Of course not! So why would anyone intentionally sin simply because grace is available to treat it? The purpose of the New Covenant was not to provide us with a license to sin, but to provide us with grace that would not only wipe away our past transgressions, but give us the power to avoid future transgressions.
