Gray was born in a house still standing on the north side of the Lawnmarket, Edinburgh, in August 1633. He was fourth son and eleventh child in a family of twenty-one, his father being Sir William Gray of Pittendrum, an eminent merchant and royalist, descended from Andrew, first lord Gray. His mother was Geils or Egidia Smyth, sister to Sir John Smith of Grothill, provost of Edinburgh from 1643 to 1646. Andrew in his childhood was playful and fond of pleasure; but while he was quite young his thoughts were suddenly given a serious turn by reflecting on the piety of a beggar whom he met near Leith. Resolved to enter the ministry, he studied at the universities both of St. Andrews and Edinburgh. He graduated at the former in 1651. Gray was one of that band of youthful preachers who were powerfully influenced by the venerable Leighton. His talents and learning favourably impressed Principal Gillespie. He was licensed to preach in 1653, and was ordained to the collegiate charge of the Outer High Church of Glasgow on 3 Nov. 1653, although only in his twenty-first year, notwithstanding some remonstrance. One of the remonstrants, Robert Baillie, refers in his Letters and Journals to the ‘high flown, rhetorical style’ of the youthful preacher, and describes his ordination as taking place ‘over the belly of the town's protestation.’ His ministry proved eminently successful, and although only of three years' duration, in the profound impression produced during his lifetime, and the sustained popularity of his published works, Gray had few rivals in the Scottish church. When he was twenty-two, Gray expressed the desire to see his Lord before his upcoming birthday. Six months later, on 8 Feb. 1656, his wish was granted. Andrew Gray died after a brief illness, of a ‘purple’ fever, and was interred in Blackadder's or St. Fergus's Aisle, Glasgow Cathedral. On the walls of the aisle his initials and date of death may be seen deeply incised. Gray married Rachael, daughter of Robert Baillie of Jerviswood, and had a son, William, born at Glasgow in March 1655, who probably died young. He had also a daughter, Rachael, who was served heir to her father on 26 June 1669. His widow remarried George Hutcheson, minister at Irvine. Many of Gray's sermons and communion addresses were taken down at the time of delivery, chiefly in shorthand by his wife, and were published posthumously. Some yet remain in unpublished manuscripts. Pre-Restoration editions are extremely rare, but a few are still extant. The following are the chief editions known:

From a manuscript collection of sixty-one other sermons, eleven were published as vol. i. of an intended series, with preface by the Rev. John Willison of Dundee, in 1746. The fifty remaining sermons appeared later in another volume as ‘Select Sermons by … Mr. Andrew Gray,’ Edinburgh, 1765, 8vo; Falkirk, 1792, 8vo. From the 1746 volume was reissued separately, with a Gaelic translation by J. Gillies, the sermon on Canticles iii. 11. Two single sermons, not apparently published elsewhere, one on Exod. xxxiv. 6, the other on Job xxiii. 3, appeared respectively at Edinburgh in 1774 and at Glasgow in 1782.
