O God of battles!
Truly, you dwell in peace,
And yet, you behold the strife of men, and work your will thereby.
It is a mystery, part of the war between good and evil, that I cannot comprehend.
And what that good and perfect will of thine is, I do not fully know;
However, I do know that you have sent us to do with all our might what our hands find to do, in the work of good; and I know that you hate cowardice.
You know that I have sought to choose the best, so far as my poor mind can determine, and to this battle I am pledged.
Give me grace to fight like a soldier of thine, without wrath and without fear.
Give me to do my duty, but give the victory where you please.
Let me live if it so be your will; let me die if it be your will -- only let me die in honor with You.
Let the truth be victorious, if not now, yet when it shall please you;
And oh! I pray, let no deed of mine delay the fulfillment of truth.
Let my work fail, if it be unto evil, but save my soul in truth.
This I ask in the strong Name of the Son of God, who is the Truth, and through your Holy Spirit, Amen.
Selah.
And here is that prayer in its original context, by George MacDonald:
Humility before the God of Truth
'Callest thou thy cousin a hypocrite?'
'No, by heaven! she is not. She is a woman, and it is easy for women to say prayers.'
'I never rode into a fight but I said my prayer,' returned Richard.
'None the less art thou a hypocrite. I should scorn to be for ever begging favours as thou. Dost think God heareth such prayers as thine?'
'Not if He be such as thou, sir Rowland, and not if he who prays be such as thou thinkest him. Prithee, what sort of prayer thinkest thou I pray ere I ride into the battle?'
'How should I know? My lord marquis would have had me say my prayers at such a time, but, good sooth! I always forgot. And if I had done it, where would have been the benefit thereof, so long as thou, who wast better used to the work, wast praying against me? I say it is a cowardly thing to go praying into the battle, and not take thy fair chance as other men do.'
'Then will I tell thee to what purpose I pray. But, first of all, I must confess to thee that I have had my doubts, not whether my side were more in the right than thine, but whether it were worth while to raise the sword even in such cause. Now, still when that doubt cometh, ever it taketh from my arm the strength, and going down into the very legs of my mare causeth that she goeth dull, although willing, into the battle. Moreover, I am no saint, and therefore cannot pray like a saint, but only like Richard Heywood, who hath got to do his duty, and is something puzzled. Therefore pray I thus, or to this effect:
'"O God of battles! who, thyself dwelling in peace, beholdest the strife, and workest thy will thereby, what that good and perfect will of thine is I know not clearly, but thou hast sent us to be doing, and thou hatest cowardice. Thou knowest I have sought to choose the best, so far as goeth my poor ken, and to this battle I am pledged. Give me grace to fight like a soldier of thine, without wrath and without fear. Give me to do my duty, but give the victory where thou pleasest. Let me live if so thou wilt; let me die if so thou wilt--only let me die in honour with thee. Let the truth be victorious, if not now, yet when it shall please thee; and oh! I pray, let no deed of mine delay its coming. Let my work fail, if it be unto evil, but save my soul in truth."
'And in truth, sir Rowland, it seemeth to me then as if the God of truth heard me. Then say I to my mare, "Come, Lady, all is well now. Let us go. And good will come of it to thee also, for how should the Father think of his sparrows and forget his mares? Doubtless there are of thy kind in heaven, else how should the apostle have seen them there? And if any, surely thou, my Lady!" So ride we to the battle, merry and strong, and calm, as if we were but riding to the rampart of the celestial city.'
Selah.
