"I am in one continued, perpetual, and uninterrupted hurry; and Divine Providence throws so much upon me that I do not see it will ever be otherwise. May I “obtain mercy of God to be faithful to the death!” I cannot say I am weary of my hurry; I only want strength and grace to do more for God than I have ever yet done.
My dear brother; The Lord of heaven, that has carried me through many trials, bless you; bless you for time, and eternity; and fit you to do service for him in his church below, and to enjoy his blissful presence in his church triumphant. My brother; “the time is short:” oh let us fill it up for God; let us “count the sufferings of this present time” as nothing, if we can but “run our race, and finish our course with joy.” Oh, let us strive to live to God. I bless the Lord, I have nothing to do with earth, but only to labour honestly in it for God, till I shall “accomplish as an hireling my day.” I think I do not desire to live one minute for any thing that earth can afford. Oh, that I could live for none but God, till my dying moment!"
A letter penned by David Brainerd to his brother John from December 28, 1745
