Nothing is so effective in keeping true Christianity alive as the yeast of zealous Christians scattered throughout the Church. Like salt, they prevent the whole body from falling into a state of decay. No one but people of this kind can revive Churches that are about to die. It is impossible to overestimate the debt that all Christians owe to zeal. The greatest mistake the leaders of a Church can make is to drive zealous people out of its congregation. By doing so they drain out the life-blood of the system, and advance the church’s decline and death. God delights in honoring zeal. Look through the list of Christians who have been used most mightily by God. Who are the people that have left the deepest and most indelible marks on the Church of their day? Who are the people that God has generally honored to build up the walls of His Zion, and also to fight the enemy at the gate? He does not use people of learning and literary talent as readily as people of zeal.
