Our Armour or Grace Must Be Kept In Exercise

[The use of our spiritual armour —put on the whole armour of God.]

          

   The fourth and last branch in the saints' furniture is, the use they are to make thereof, ‘put on the whole armour of God.’  Briefly, what is this duty, put on?  These being saints, many of them at least, whom he writes to, it is not only putting on by conversation, what some of them might not yet have, but also, he means they should exercise what they have.  It is one thing to have armour in the house, and another thing to have it buckled on; to have grace in the principle, and grace in the act.  So that our instruction will be, 

[Our armour or grace must be kept in exercise.]

             Doctrine.  It is not enough to have grace, but this grace must be kept in exercise.  The Christian's armour is made to be worn; no laying down, or put­ting off our armour, till we have done our warfare, and finished our course.  Our armour and our garment of flesh go off together; then, indeed, will be no need of watch and ward; shield or helmet.  Those military duties and field-graces—as I may call faith, hope, and the rest—shall be honourably discharged. In heaven we shall appear, not in armour, but in robes of glory.  But here these are to be worn night and day; we must walk, work, and sleep in them, or else we are not true soldiers of Christ.  This Paul professeth to endeavour.  ‘Herein do I exercise my­self, to have always a conscience void of offence toward God, and toward men,’ Acts 24:16.  Here we have this holy man at his arms, training and exer­cising himself in his postures, like some soldier by himself handling his pike, and injuring himself before the battle.  Now the reason of this is,

             First.  Christ commands us to have our armour on, our grace in exercise.  ‘Let your loins be girded about, and your lights burning,’ Luke 12:35.  Christ speaks either in a martial phrase, as to soldiers, or in a domestic, as to servants.  If as to soldiers, then let your loins be girded and your lights burning, that is, we should be ready for a march, having our armour on—for the belt goes over all—and our match lighted, ready to give fire at the first alarm of temp­tation.  If as to servants, which seems more natural, then he bids us, as our master that is gone abroad, not through sloth or sleep [to] put off our clothes, and put out our lights; but [to] stand ready to open when he shall come, though at midnight.  It is not fit the Master should stand at the door knocking, and the servant within sleeping.  Indeed there is no duty the Christian hath in charge, but implies this daily exercise: ‘pray’ he must—but how?—‘without ceasing;’ ‘rejoice’—but when?—‘evermore;’ ‘give thanks’ —for what? ‘in everything,’ I Thes. 5:16-18.  The shield of faith, and helmet of hope, we must hold them to the end, I Pet. 1:13.  The sum of all which is, that we should walk in the constant exercise of these duties and graces.  Where the soldier is placed, there he stands, and must neither stir nor sleep till he be brought off.  When Christ comes, that soul shall only have his blessing whom he finds so doing.
