The mystery of faith opened up. Or Some sermons concerning faith : (two whereof were not formerly printed,) wherein the nature, excellency, and usefulnesse of that noble grace is much cleared, and the practice thereof most powerfully pressed. Whereunto are added three other sermons, two concerning the great-salvation. (one of these not formerly printed) and a third concerning death. - Gray, Andrew, 1633-1656 (Early English books online., 1660)
