Antinomianism is the idea that because Jesus has come, believers do not need to obey God’s moral law. The term antinomian comes from two Greek words: anti (against) and nomos (law). Antinomianism claims that, because Christians are saved by grace and not under the Mosaic Law, they are no longer bound to obey any moral commands. The Bible teaches that while we are not under the Mosaic Law, God’s moral standards still reflect His character and remain binding. Paul warns against using grace as an excuse to sin (Romans 6:1–2) and affirms that faith establishes the law, not nullifies it (Romans 3:31). Jesus said He did not come to abolish the Law but to fulfill it (Matthew 5:17) and that those who love Him will keep His commandments (John 14:15). Though we are not saved by law-keeping, those who are truly saved will be marked by obedience (1 John 2:3-6). In short: Christians are freed from sin, not freed to sin.
The term antinomian comes from two Greek words: anti (against) and nomos (law). An Antinomian, then, is someone who is against obeying God’s laws. They claim that God saves by grace and not by obedience, so they feel free from even God’s moral laws. While they rightly understand that salvation is by grace alone, they miss that 1) even the Old Testament saints were saved by grace and not because they obeyed the Mosaic law and 2) God demands His children to live righteously, which means obeying Him.
Antinomianism is alive and well in many Christian circles, often cloaked in the language of grace. But grace does not free us from obedience; it frees us to obey. A Christian who lives with no concern for God’s commands has misunderstood the gospel itself and has real reason to be concerned about the genuineness of his or her salvation.
While we are not under the Mosaic Law, we are still called to reflect God’s holy character which shines through all of His commands to us. That includes honoring what He has declared to be right and wrong because His moral standards are not outdated or optional.
True faith results in transformation. The same grace that forgives us also trains us to say no to sin and yes to righteousness. This doesn’t mean we will obey perfectly. Take heart: True believers need continual forgiveness (1 John 1:8-10), but we will move more and more toward holiness over time.
If we minimize God’s moral law, we cheapen grace and redefine love. Jesus said, “If you love Me, you will keep My commandments” (John 14:15). Those are literally words to live by.
