The Bible commands us to live holy lives. To be holy, among other things, involves being set apart to God, which entails separation from the world. I think it can be a challenge for Christians these days to live holy and preach holiness without being called legalistic. So I wonder how we should define the difference between legalism and holiness. I have some ideas of my own, but I would like to hear your thoughts. What is the difference between legalism and holiness? I think that holy living has been discouraged in the church because of Christians being so quick to call believers who try to practice and preach holiness, legalistic. I also think that some churches and people have been able to get away with legalism under the guise of holy living. What are your thoughts?
