The Sovereign Grace Advent Testimony (SGAT) is a Reformed Christian organisation begun in 1918 (107 years ago) (1918) in the United Kingdom.
SGAT's stated purpose is the promotion and diffusion of the faith, being the doctrine of God's sovereign grace in the matter of man's salvation, and the truth of the second advent of the Lord Jesus Christ.
The Sovereign Grace Advent Testimony publish books by authors such as Benjamin Wills Newton, George Müller, Samuel Prideaux Tregelles and Charles Haddon Spurgeon.
Regular monthly meetings are held at New Life Bible Presbyterian Church in West Kilburn, London, including two conferences, in the Spring and Autumn.
The Sovereign Grace Advent Testimony was formed after World War I, when a group of men got together and expressed the view that rather than leave such vital testimony to magazines, an organisation should be set up to bear witness to the revealed truth of the doctrine of free and sovereign grace and the personal, post-tribulational, pre-millennial return of the Lord Jesus Christ.
