Of Rest in God Who Ever Works, and Yet is Ever at Rest
52. For even then shall You so rest in us, as now You work in us; and thus shall that be Your rest through us, as these are Your works through us. But You, O Lord, always work, and are always at rest. Nor do You see in time, nor do You move in time, nor do You in time; and yet You make the scenes of time, and the times themselves, and the rest which results from time.
