“DEAR BROTHER,—1. Consider, in the first place, the great importance, to a preacher, of a blameless life. You must, like Timothy, ‘flee youthful lusts,’ as you would escape from beasts of prey; for there are kinds of beasts, living in the wilderness of man’s corruption, that will charm, by means of their beauteous colours, those that walk among their haunts; there is no safety but by keeping from them, and adhering to such as live by faith, and watch, and pray. It will be well for you, while you travel through the coppice of youth, to keep from all appearance of evil. May you have grace to pass through the coppice of forbidden trees, without cutting your name into the bark of one of them, or you may be upbraided, at critical times, by those who may wish to prove that you are not better than themselves; even the _iota_, inserted by your hand, may be produced after many years.
“2. I remember the words of Luther, that _reading_, _prayer_, and _temptation_ are necessary to strengthen, and to purify the talents of a minister. Read, to extend your general knowledge, especially as to the plan of redemption, according to the Scriptures, in all its parts, from the election to the glorification; that you may, like a spiritual watchmaker, know all the relative cog-wheels, and be able to open them in the pulpit, and to connect them all by faith, hope, and charity, that they may occupy their own places, and exhibit their true results on the dial-plate; thus proving yourself a workman that needeth not to be ashamed, rightly dividing the word of truth. Be not like that thrasher, who presumptuously took his watch to pieces in the barn, and could not put it together again, but was obliged to carry it home in his handkerchief. The messengers of God, described in the book of Revelations, are full of eyes behind, and before. You must use prayer to fetch strength out of Christ, like the homer to carry home the manna in, or the water-pot of the woman of Samaria. Without the prayer of faith, the preacher will have ‘nothing to draw with,’ from the well that is deep,—even _the deep things of God_. Temptation is requisite, to prove the nature of the metal of the preacher’s character, and doctrine,—‘approved of God.’ The piece of gold, in every true minister’s ministry, must be tried in some furnace, prepared by Divine Providence. He must, therefore, do the work of an evangelist, fulfil his ministry, endure hardness, and affliction, and thus prove himself a good soldier of Jesus Christ.
