How do I stop thinking like a legalist? I have been reading a lot of Baptist materials lately, and always seem to think like a legalist.
You do recognize that what you read affects your thought process. With that in mind, the answer to your question amounts to changing your reading material.
Legalism shows itself in different ways: trying to accomplish what only the gospel can, labeling things “sinful” when God has not done so and using the gospel as a club to change behavior.
In addition to reading the Bible, I encourage you to use materials that do not confuse law and gospel. For starters, you can consider reading Forward in Christ, our monthly magazine. God bless your reading!
