To be a Christian is to be a traveller; like that of the Israelite people in the desert of Sinai: we live in tents, not houses, for spiritually we are always on the move. We are on a journey through the inward space of the heart, a journey not measured by the hours of our watch or the days of the calendar, for it is a journey out of time into eternity.
