Many low and carnal considerations may work men to watch their words, their lives, their actions; as hope of gain, or to please friends, or to get a name in the world, and many other such like considerations. Oh! but to watch our thoughts, to weep and lament over them, etc., this must needs be from some noble, spiritual, and internal principle, as love to God, a holy fear of God, a holy care and delight to please the Lord.

—Charles H. Spurgeon
