17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God.
The fifth piece of armour that God has given to Christians for their spiritual battle is “the helmet of salvation”. The helmet protected the head, the most vital and most often targeted part of the soldier’s body. Scarcely would a warrior rush off to battle without taking his helmet with him. Even modern troops always have their helmets on when they report for duty, which is all the more needful when in the thick of battle.
But what is the helmet of salvation? To be sure, the helmet of salvation is not worn as a means to getting saved. Rather, it means being assured of one’s salvation. It is all about a Christian’s need to cultivate a strong assurance regarding his salvation though Satan’s attacks at times may seem so overwhelming. It is the assurance that he will neither be debilitated nor destroyed in the midst of battle.
In order to grasp the significance of “the helmet of salvation”, one must understand the three aspects of salvation as found in the Scriptures; i.e. those who are justified will be sanctified and ultimately, glorified. When Satan harasses and confronts us with numerous trials, let us look forward to the day when we shall be with our Lord Jesus forever. The day is coming when sin and Satan can no longer molest us. So let us never quit, no matter how malicious the devil’s threat is. We must fight on as we continue to don this helmet of salvation until the day of glorification.
The sixth piece of armour that God has given to Christians for their spiritual battle is “the sword of the Spirit”. The first five components of God’s armour that Paul has enumerated thus far have been primarily for defensive purposes. This one last piece, however, gives both defensive and offensive might to those who carry it to battle. The Word of God is the sword of the Spirit because it is the Holy Spirit who handed this sword over to God’s people for their use. Because the Word of God wields the omnipotent power of the Spirit, it helps us to put our enemy, the devil, to flight. That was what happened to Satan who came to tempt the Lord Jesus in the wilderness (Matthew 4:1-11). Jesus merely brandished the Spirit’s sword by saying, “Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve” (Matthew 4:10). Then the devil fled and the battle ended, just like that.
