Preface to John Gillies' Historical Collections and Accounts of Revival. Some who are really seeking to feed the flock , and to save souls, are led to exhaust their energies upon external duties and labors, overlooking the absolute necessity of enriching, ripening, filling, elevating their own souls by prayer and fasting. On this account there is much time wasted and labor thrown away. A single word , coming fresh from lips that have been kindled into heavenly warmth, by near fellowship with God, will avail more than a thousand others. Did Christ's faithful ministers act more on this principle, they would soon learn what an increased fruitfulness and power are thereby imparted to all their labours . Were more of each returning Saturday spent in fellowship with God, in solemn intercession for the people, in humiliation for sin , and supplication for the outpouring of the Spirit,—our Sabbaths would be far more blest.
