. . .a Christianity without an altar is a Christianity without power, impotent to move the world or to control the individual heart, inadequate to meet the needs and the cravings of men. Where are the decaying Christians? Where are the Christians who have let go the central fact of an incarnate sacrifice for the world’s sin? The answer to the two questions is the same. Wherever you find a feeble grasp of that central truth or a faltering utterance of it on the part of the preachers, there you find deadness and formality. – Alexander Maclaren (1826-1910), from a meditation on Hebrews 13.10, 15.
