We may, perhaps, trace a certain progress in the enumeration of the various pieces of the Christian armour in this context. Roughly speaking, they are in three divisions. There are first our graces of truth, righteousness, preparedness, which, though they are all conceived as given by God, are yet the exercises of our own powers. There is next, standing alone, as befits its all-comprehensive character, faith which is able to ward against and overcome not merely this and that temptation, but all forms of evil. That faith is the root of the three preceding graces, and makes the transition to the two which follow, because it is the hand by which we lay hold of God's gifts. The two final parts of the Christian armour are God's gifts, pure and simple--salvation and the word of God. So the progress is from circumference to centre, from man to God. From the central faith we have on the one hand that which it produces in us; on the other, that which it lays hold of from God. And these two last pieces of armour, being wholly God's gift, we are bidden with especial emphasis which is shown by a change in construction, to take or receive these. I. The Salvation. Once more Old Testament prophecy suggests the words of this exhortation. In Isaiah's grand vision of God, arising to execute judgment which is also redemption, we have a wonderful picture of His arraying Himself in armour. Righteousness is His flashing breastplate: on His head is an helmet of salvation. The gleaming steel is draped by garments of retributive judgment, and over all is cast, like a cloak, the ample folds of that 'zeal' which expresses the inexhaustible energy and intensity of the divine nature and action. Thus arrayed He comes forth to avenge and save. His redeeming work is the manifestation and issue of all these characteristics of His nature. It flames with divine fervour: it manifests the justice which repays, but its inmost character is righteousness, and its chief purpose is to save. His helmet is salvation; the plain, prose meaning of which would appear to be that His great purpose of saving men is its own guarantee that His purpose should be effected, and is the armour by which His work is defended. The Apostle uses the old picture with perfect freedom, quoting the words indeed, but employing them quite differently. God's helmet of salvation is His own purpose; man's helmet of salvation is God's gift. He is strong to save because He wills to save; we are strong and safe when we take the salvation which He gives.
