How do we know the gospel of peace is true?

The gospel of peace is grounded in the truth of God's Word which has been validated through the life, death, and resurrection of Jesus Christ. Scriptures such as Romans 5:1 affirm that through faith in Christ, we are justified and thus have peace with God. This peace signifies that the enmity caused by sin has been resolved. Additionally, the transformation experienced in the lives of believers acts as a testimony to the power and truth of the gospel, as they move from spiritual poverty to richness in Christ, embodying the peace the gospel promises.
