The Confessions And Letters Of St by St. Augustine
Chapter XXXVII.--Of Rest in God Who Ever Worketh, and Yet is Ever at Rest.
52. For even then shalt Thou so rest in us, as now Thou dost work in us; and thus shall that be Thy rest through us, as these are Thy works through us. But Thou, O Lord, ever workest, and art ever at rest. Nor seest Thou in time, nor movest Thou in time, nor restest Thou in time; and yet Thou makest the scenes of time, and the times themselves, and the rest which results from time.
