From Lectures to My Students, “The Minister’s Self Watch” (p. 12 in the Pilgrim ed.):
“As is the workman, such will the work be. To face the enemies of truth, to defend the bulwarks of the faith, to rule well in the house of God, to comfort all that mourn, to edify the saints, to guide the perplexed, to bear with the froward, to win and nurse souls–all these and a thousand other works beside are not for a Feeble-mind or a Ready-to-halt, but are reserved for Great-heart whom the Lord has made strong for himself. Seek then strength from the Strong One, wisdom from the Wise One, in fact, all from the God of all.”
