Such timeless space is called kairos time, a term which comes to us from the ancient Greeks, who designated another kind of time as chronological (from chronos). Kairos moments are described as occurring in between chronological moments, and they offer special or potent opportunities. In Christian thought, kairos time marks an appointed time in the purpose of God. Some churches understand kairos time to be in effect when the prayers and songs of human worship intersect with the eternal worship of heavenly angels. Kairos time is ripe and rich and fulfilling. In a kairos moment, time seems to stand still.
