In expositing Ephesians 6:10-20, William Gurnall seeks to distill every ounce of truth from the mines of spiritual warfare. It is a tremendous work, both in its length and in its content.
In the present section, Gurnall is describing the need for the whole armor of God (see Eph. 6:11). Up to this point, he has made mention of the need for the armor, what the armor consists of, and why the Christian must bear it.
Now Gurnall focuses on the extent of the armor or the completeness of it. He discusses it in a “threefold respect.” (Gurnall, 58) These are:
- “FIRST. He must be armed in every part cap-a-pie, soul and body, the powers of the one, and senses of the other, not any part left naked.” (Gurnall, 58)
- “SECOND. The Christian must be in complete armour, in regard of the several pieces and weapons, that make up the whole armour of God.” (Gurnall, 58)
- “THIRD. The entireness of the saint’s armour may be taken not only for every part and piece of the saint’s furniture, but for the completeness and perfection of every piece.” (Gurnall, 83)
These are excellent points that well deserve our attention. We will examine these briefly.
“FIRST. He must be armed in every part cap-a-pie, soul and body, the powers of the one, and senses of the other, not any part left naked.” (Gurnall, 58)
In other words, the whole armor involves the whole body. Every inch must be protected in order to wage war against the enemy of our souls. Gurnall remarks, “Our enemies are on every side, and so must our armour be.” (Gurnall, 58)
He notes several examples of individuals in the Scripture who had one area unprotected. Ahab was killed with a small dart. “Eve looked but on the tree, and a poisonous dart struck her to the heart,” write Gurnall. (Gurnall, 58)
Are we not as prone to sin as they? Must we not bear the whole armor of God, and ensure every part of our bodies are covered and protected from the attacks of the devil? How foolish we are to think that we are more than capable of handling an enemy who has practiced wickedness almost as long as time has existed! How arrogant and haughty are we that we believe we can do what the powerful angel Michael could not! (Jude 9)
Brothers and sisters, let us put on the whole armor of God.
“SECOND. The Christian must be in complete armour, in regard of the several pieces and weapons, that make up the whole armour of God.” (Gurnall, 58)
Continuing on, Gurunall comments on the need to build upon the armor of God. That is, the need to develop the graces with which God has lavished upon the believer. He spends the majority of this section in 2 Peter 1:5-7, which reads:
5 For this very reason, make every effort to supplement your faith with virtue, and virtue with knowledge, 6 and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, 7 and godliness with brotherly affection, and brotherly affection with love.
Gurnall notes how the Scriptures describe the increasing effect of growing in grace. In putting on the whole armor, the Christian must not leave one piece off. He provides a brief exposition of that passage (a marvelous one) and then applies it to the understanding of the Christian’s armor. Each piece, each grace, if you will, must be donned. The enemies of our soul are many, multi-talented and intrinsically evil. As we put on this armor, we must put all of it on. We must don the graces of our Lord Jesus Christ in order to stand against the attacks of the slithering serpent.
“THIRD. The entireness of the saint’s armour may be taken not only for every part and piece of the saint’s furniture, but for the completeness and perfection of every piece.” (Gurnall, 83)
The final item Gurnall discusses concerns the sharpening of the tools, the increasing of their effectiveness. The blade of the knight must be continually sharpened in order to maintain its effectiveness in battle. Likewise, the Christian’s armor must be maintained.
Gurnall describes the situation,
“The Christian had need have an armourer’s shop at hand to make up his loss, and that speedily, for Satan is most like to fall on when the Christian is least prepared to receive his charge.” (Gurnall, 61)
The Christian’s armor must be at the ready at all times, for the devil is a tireless enemy. Therefore the Christian must be about the protection and development of his armor. This is due to the nature of grace, “Because grace is subject to decays,” remarks Gurnall. (Gurnall, 61)
We are in the work of sanctification, daily becoming more like Jesus Christ, which necessarily involves the armor of God.
How is your armor, Christian? Are you wearing all the armor of God? Are you and I constantly building upon the faith, as described by our brother Peter? Are we watching our armor, ensuring it is equipped and maintained?
As I read this section, I was reminded of the fierceness of the battle. Christians, we need to remember that our adversary is walking around looking for people to devour. Therefore, let us put on the whole armor of God.
