We shall all do well to remember the charge: “Forsake not the assembling of yourselves together, as the manner of some is.” (Heb. 10:25). Never to be absent from God’s house on Sundays, without good reason—never to miss the Lord’s Supper when administered in our own congregation—never to let our place be empty when means of grace are going on, this is one way to be a growing and prosperous Christian. The very sermon that we needlessly miss, may contain a precious word in season for our souls. The very assembly for prayer and praise from which we stay away, may be the very gathering that would have cheered, established, and revived our hearts. We know very little how dependent our spiritual health is on little, regular, habitual helps, and how much we suffer if we miss our medicine.
