Everyone knows that legalism is bad. But what exactly is legalism? Is it legalistic to obey God's laws? Is it legalistic when we obey God too much or too carefully? On the narrow road that leads to eternal life, legalism is the ditch on one side of the road. The ditch on the other side is antinomianism. Determined to avoid misusing God's laws and becoming legalistic, some neglect God's laws altogether and become antinomian. Legalism is bad, but antinomianism is equally bad. Understanding legalism requires that we understand antinomianism, and this booklet explains both concepts.
