An unfortunate trend in today's Christianity is the de-emphasis of holiness in favor of a perverted view of "grace." The essence of the Gospel is this: I used to be evil, but God made a way for me to be good. But the average "Christian" has been duped into believing that the Gospel is this: I was evil, but God made a way for me to keep being evil and get away with it. We treat grace as if it's a magic eraser, yet we never get clean because we haven't actually repented and submitted fully to Him in total obedience. Are we saved "by grace through faith"? Absolutely! But that grace is not just freedom from the guilt of sin, but also the power of the Holy Spirit to overcome sin. And that faith is not merely believing "that" Jesus died for us; it is believing "in" Jesus to empower us by His Spirit to live lives that are pleasing to God."Holiness is Not Optional" is an invitation to rediscover essential truths about the Christian walk, to reclaim our full inheritance of grace, and to release the power of God to transform our lives. A reformation of holiness is upon us, and this book challenges its readers to join it.
