Paul’s letter to the Galatians addresses a critical issue: the temptation to add to the simple gospel of Jesus Christ. He was astonished that the Galatians had quickly abandoned the core message for a legalistic version. Paul emphasizes that there is only one true gospel with a supernatural origin, outcome, and opposition. He pronounces a strong warning against those who distort this message. The simple gospel is enough—we don’t need to clean up our lives before coming to Christ or add works to faith. We are called to embrace this simplicity and protect the original message.
