The gospel, as referenced among the various modifiers by New Testament writers, is twice called the gospel of peace. This designation highlights its role as a dynamic message, carrying the power of God for salvation to everyone who believes. The gospel of peace serves as a vehicle through which God saves us, provided we live by faith, embodying a stored energy ready to propel believers toward eternal life. It instructs us in righteousness, revealing God's will through faith, so that we may live faithfully and do what is right and godly.

In the profound moments following His resurrection, Jesus Christ imparted a message of peace to His disciples, as recorded in John 20:19-21. On the evening of the first day of the week, with the doors shut for fear of the Jews, Jesus appeared in their midst and declared, "Peace be with you." This greeting, rooted in the Hebrew word shalom, was no mere salutation but a profound endowment of peace as God's gift, akin to the English phrase "God bless you." It signified the peace achieved through His death and resurrection, a peace with God that humanity, naturally at war with the Divine, could not attain on its own terms. Jesus, having gone to the cross and risen from the dead, dispensed this real peace to those who believed in Him, a peace that surpasses worldly definitions and offers reconciliation with God on His terms alone. This peace, offered during the Feast of Unleavened Bread, carries additional significance, marking not only peace with God but also the peace of God—a divine tranquility that guards hearts and minds, as described in Philippians 4:6-7. To the disciples, who had endured the trauma of His arrest, crucifixion, and the bewildering news of an empty tomb, Jesus' words, "Peace be with you," brought solace amid fear and agitation. This gift of peace, one of many results of His sacrifice, stands as a cornerstone for their mission, enabling them to face life's distresses with divine assurance. Moreover, Jesus linked this peace to their commissioning in John 20:21, repeating, "Peace to you! As the Father has sent Me, I also send you." This connection underscores that true peace, both inwardly and outwardly, is essential before one can effectively proclaim the gospel of peace to others. This gospel encompasses God's commandments, statutes, and laws, forming a foundation necessary for genuine peace. Without experiencing and assuring themselves of Christ's peace—peace of conscience through His death that banishes sin, and peace of mind through His resurrection that banishes doubt—the church cannot fulfill its call to preach the coming Kingdom of God. Thus, the gospel of peace is both a personal transformation and a communal mission, rooted in the reconciliation and tranquility Christ provides.

In the midst of our spiritual warfare, we are called to equip ourselves with the armor of God, as outlined in Ephesians 6:15, where we are to have our feet shod with the preparation of the gospel of peace. This gospel is not merely a message to be shared verbally, but a way of life that we must embody. It serves as our foundation, providing sure footing against the hatred and conflict that define this world under Satan's influence. We are to demonstrate the true path to peace through our actions and interactions. The essence of this gospel of peace is further detailed in Romans 12:17-20, where we are instructed to repay no one evil for evil, but to consider what is good in the sight of all men. As much as it depends on us, we must live peaceably with all, refraining from personal vengeance and leaving retribution to God, for He alone knows the measure of justice. Instead, if our enemy hungers, we are to feed him; if he thirsts, we are to give him drink, thereby setting an example of peace that may transform hearts. Moreover, Romans 13:1-14 expands on this lifestyle, urging us to be subject to governing authorities as they are appointed by God, rendering to all what is due—taxes, customs, fear, and honor. Above all, we owe love to one another, for love fulfills the law and does no harm to a neighbor. We are to cast off the works of darkness, putting on the armor of light and walking properly, clothed in the Lord Jesus Christ, making no provision for the flesh to fulfill its lusts. This is the gospel of peace we proclaim through our daily conduct, standing firm in the battle against evil by overcoming it with good.
