What does the Bible say about preaching one gospel?

The Apostle Paul emphasizes the importance of preaching one gospel in 2 Corinthians 11, where he expresses his concern for the believers at Corinth. Paul states, 'I have espoused you to one husband,' indicating that he has presented them with the singular message of Christ. This underscores the reality that the true gospel is focused solely on the death and resurrection of Jesus Christ. In a world filled with alternative messages and subtle distortions of the truth, it is paramount for the church to adhere to the singular gospel which is the power of God unto salvation.
