What does the Bible say about the gospel of peace?

In Ephesians 6:15, the Apostle Paul instructs believers to have their feet shod with the preparation of the gospel of peace. This imagery signifies that the gospel serves as a firm foundation for Christians, enabling them to stand strong against spiritual opposition and the deceptions of Satan. The gospel brings peace with God, reconciling the believer to the Father and making them ready to withstand challenges. It is an essential part of the Christian armor, providing both protection and confidence in spiritual warfare.
