There is another idea involved in this description. The soldiers are not only marked by glad obedience, but that obedience rests upon the sacrifice of themselves. The word here rendered 'willing' is employed throughout the Levitical law for 'freewill offerings.' And if we may venture to bring that reference in here, it carries us a step farther in this characterisation of the army. This glad submission comes from self-consecration and surrender. It is in that host as it was in the army whose heroic self-devotion was chaunted by Deborah under her palm-tree, 'The people willingly offered themselves.' Hence came courage, devotion, victory. With their lives in their hands they flung themselves on the foe, and nothing could stand against the onset of men who recked not of themselves. There is one grand thing even about the devilry of war--the transcendent self-abnegation with which, however poor and unworthy may be the cause, a man casts himself away, 'what time the foeman's line is broke.' The poorest, vulgarest, most animal natures rise for a moment into something like nobility, as the surge of the strong emotion lifts them to that height of heroism. Life is then most glorious when it is given away for a great cause. That sacrifice is the one noble and chivalrous element which gives interest to war--the one thing that can be disentangled from its hideous associations, and can be transferred to higher regions of life. That spirit of lofty consecration and utter self-forgetfulness must be ours, if we would be Christ's soldiers. Our obedience will then be glad when we feel the force of, and yield to, that gentle, persuasive entreaty, 'I beseech you, brethren! by the mercies of God, that ye present your bodies a living sacrifice.' There is 'one Sacrifice for sin for ever'--which never can be repeated, nor exhausted, nor copied. And the loving, faithful acceptance of that sacrifice of propitiation leads our hearts to the response of thank-offering, the sacrifice and surrender of ourselves to Him who has given Himself not only to, but for us. It cannot be recompensed, but it may be acknowledged. Let us give ourselves to Christ, for He has died for us. Let us give ourselves to Christ, for only in such surrender do we truly find ourselves. Let us give ourselves to Christ, for such a sacrifice makes all life fair and noble, and that altar sanctifies the gift. Let us give ourselves to Christ, for without such sacrifice we have no place in the host whom He leads to victory. 'Thy people shall be willing offerings in the day of Thy power.'
Still further, another remarkable idea may be connected with this word. By a natural transition, of which illustrations may be found in other languages, it comes to mean '_free_,' and also '_noble_.' As, for instance, it is used in the fifty-first Psalm, 'Uphold me with Thy _free_ Spirit'--and in the forty-seventh, 'The _princes_ of the people are gathered together.' And does not this shading of significations--willing sacrifices, free, princely--remind us of another distinctly evangelical principle, that the willing service which rests upon glad consecration raises him who renders it to true freedom and dominion? Every man enlisted in His body-guard is noble. The Prince's servants are every other person's master. The King's livery exempts from all other submission. As in the old Saxon monarchies, the monarch's domestics were nobles, the men of Christ's household are ennobled by their service. They who obey Him are free from every yoke of bondage--'free indeed.' All things serve the soul that serves Christ. 'He hath made us kings unto God.'
II. The soldiers are priests.
That expression, 'in the beauties of holiness,' is usually read as if it belonged either to the words immediately preceding, or to those immediately following. But in either case the connection is somewhat difficult and obscure. It seems better regarded as a distinct and separate clause, adding a fresh trait to the description of the army, and what that is we need not find any difficulty in ascertaining. 'The beauties of holiness' is a frequent phrase for the sacerdotal garments, the holy festal attire of the priests of the Lord. So considered, how beautifully it comes in here! The conquering King whom the psalm hymns is a Priest for ever; and He is followed by an army of priests. The soldiers are gathered in the day of the muster, with high courage and willing devotion, ready to fling away their lives; but they are clad not in mail, but in priestly robes--like those who wait before the altar rather than like those who plunge into the fight--like those who compassed Jericho with the ark for their standard, and the trumpets for all their weapons. We can scarcely fail to remember the words which echo these and interpret them: 'The armies which were in heaven followed Him on white horses, clothed in fine linen, white and clean'--a strange armour against sword-cut and spear-thrust.
