Robert Murray M’Cheyne (1813-1843), above everything else, was a man of prayer.
“How may I teach by letters, by books, by tracts? Dark, cold, and powerless in themselves, yet, filled with the Spirit of God, they may convey life, and light and gladness, into thousands of dwellings. The smallest tract may be the stone in David’s sling. In the hands of Christ, it may bring down a giant.” –Robert Murray M’Cheyne
“’What do you think’ a young man said to the caretaker, ‘is the secret of Mcheyenes great ministry? what was the secret of the power in the pulpit?’ The caretaker looked at the minister, he said nothing for a moment but he just conducted the minister into the vestry. Now he said, ‘kneel down by the chair’ and the somewhat amused minister knelt by the chair. And in a most solemn tone the caretaker said: ‘Now then.. start to weep. raise your eyes to heaven and cry to God. Ohh God bless me! Ohh God use me! OHH GOD I cannot go up to yonder pulpit until I know I have the might annointing of the Spirit resting upon me.’ And looking into the face of that visiting preacher with tear filled eyes the caretaker said: ‘That dear friend is the secret of the ministry of Robert Murray M’Chyene, He was a man of prayer.’”
