What Is Legalism and Why Is It a Problem?

Legalism is the belief that a person can earn favor with God or become righteous through rule-keeping and religious performance, a problem the New Testament repeatedly confronts because it distorts grace and can foster pride or despair.

Biblical explanation

Jesus condemned the Pharisees for meticulously tithing even small herbs while neglecting “the weightier matters of the law,” such as judgment, mercy, and faith (), showing that legalism can focus on minor external details while missing the heart of God's law entirely. Paul confronted a similar problem in Galatia, warning believers not to seek justification through the law after having begun in the Spirit (), since this approach denies the sufficiency of Christ's finished work. Legalism can produce either pride, when a person feels they have kept enough rules to be acceptable, or despair, when they inevitably fail to keep every standard perfectly. The alternative Scripture offers is grace received by faith, followed by obedience that flows from love and gratitude rather than fear or self-righteous effort ().

In brief

Jesus condemned the Pharisees for meticulously tithing even small herbs while neglecting “the weightier matters of the law,” such as judgment, mercy, and faith (), showing that legalism can focus on minor external details while missing the heart of God's law entirely.
