Jonathan Edwards (1703-1758) was ordained to the ministry of the Congregational Church, at Northampton, Massachusetts, in 1727, after an experience of conversion. His Ministry was blessed by a remarkable religious revival, which led to his writing several books on the subject minutely analyzing the experience. Among them was the work Distinguishing marks of a work of the Spirit of God offered here in abridged form and in contemporary English. The full work is available from the Banner of Truth Trust, 3 Murrayfield Road, Edinburgh EH12 6EL. Unwilling to permit unconverted people to receive Communion, Edwards was removed from Northampton in 1749. He then began a missionary ministry, during which time he wrote several of his most important works.
