Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, and with your feet fitted with the readiness that comes from the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. Take the helmet of salvation and the sword of the Spirit, which is the word of God. And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints. (Eph.6:13-18)
Paul continues to use an analogy between the armor worn by Roman soldiers who were everywhere in Paul’s world and the spiritual armor we need to wear to overcome the enemy in our world. He began with a belt of truth, moved to a breastplate of righteousness and now addresses the shoes of the soldier declaring that our “feet should be fitted with the readiness that comes from the gospel of peace.” The ordinary foot soldier wore “clavata” which were sandals with nails protruding from the sole that gave them strategic traction in loose dirt when climbing or holding their ground. That is probably what Paul had in mind.
The word “readiness” means to always be ready for action – ready to move, ready to fight, ready to defend, and ready to fulfill the mission. In relation to the “gospel of peace,” we must always be ready to defend the gospel, stand on the gospel, and declare the gospel. In many ways, the gospel simply is the good news that through the sacrifice of Jesus, man can make peace with God and be reconciled by the grace of a God who longs to restore his relationship with each of us. It is both an offensive and defensive weapon.
It is defensive when the enemy comes to accuse and condemn. When he schemes to create doubt in our heart about our relationship with God, the message of the gospel should continually reassure us of our relationship with Him. Many believers forget the message of the gospel of grace because they have not shared it enough with others to write in permanently on their own hearts. When Satan comes to whisper that our spiritual performance has not been sufficient for salvation we must stand on the message of the gospel that our salvation has never been about our performance but about his sacrifice.
As an offensive weapon, it is the weapon that constantly and powerfully takes ground from the enemy. When pushing back the boundaries of darkness, the first victory must be in the hearts of men who hear and are captured by the good news of Jesus. When enough hearts have been surrendered to Jesus then families surrender. When enough families surrender then culture surrenders. When enough of the culture has surrendered then entire nations enter the kingdom of light.
The church’s primary mission is to preach the gospel and make disciples of all nations (Mt.28:18-20). Notice that the command of the Great Commission is to make disciples of entire nations not just a few individuals within a nation. If we are not taking ground we are loosing ground. The church quit taking ground in America 50 years ago and now we have lost huge chunks of cultural real estate. Only the passionate and faithful preaching of the gospel of peace will retake that ground and return righteousness to America and America to God. The church in America took off its sandals but needs to cinch them up again with a readiness to declare the Lordship of Jesus with a demonstration of power. The church has been on the defensive in America and Western Europe in recent decades but has the power in Christ to put Satan on the run if we have the will. The gospel of peace is the power of God for salvation (Rom.1:16) and the truth of that gospel enable us not only to stand but also to advance.
