Why is maintaining the truth of the gospel important for Christians?

The truth of the gospel is paramount because it centers on the reality that our justification is found in Christ alone. The apostle Paul placed great importance on this when he confronted Peter, showing that compromising the truth for the sake of unity is unacceptable. When the truth is diluted, it can lead to false beliefs about salvation and righteousness. Believers are called to be zealous for the gospel, as any deviation from its core message jeopardizes the foundation of our faith and misrepresents God's redemptive work through Christ.
