There remaineth therefore a rest to the people of God. -Hebrews 4:9

How weary must Israel have been in the wilderness! How tired must have been the soles of their feet with their constant journeyings! They were not in a place of repose, luxury, and rest, but in a land of journeying, and weariness, and trouble. I think I see them traveling, wiping frequently the burning sweat from their brows, and saying, “O that we had a habitation where we might rest! O that we could enter a land of vines and pomegranates, a city where we might enjoy immunity from alarm! God has promised it to us, but we have not found it. There remaineth a rest for the people of God; O that we might find it.” Christian! God is your habitation in this sense. He is your rest; and you will never find rest except in Him. I defy a man who has no God to have a soul at rest. He who has not Jesus for his Saviour, will always be a restless spirit…

There is a holy calm and sweet repose which the Christian only knows, something like the slumbering stars up there in beds of azure; or like the seraphic rest which we may suppose beatified spirits have when they before the throne continually bow; there is a rest so deep and calm, so still and quiet, so profound, that we find no words to describe it. You have tried it, and can rejoice in it.~ C.H. Spurgeon
