Thomas Boston, Works, 5:19 (The Art of Man-Fishing):
A man that knows a way, and can do well enough without a guide, needs not follow another. And surely the want of this is the reason why many run before Christ, and go farther than his example ever called them; and others take a way altogether different from Christ’s way, which is the product of their own conceited hearts and airy heads. But thou, O my soul, acknowledge thyself as a child in these matters, that cannot go unless it be led; as a stranger in a desert place, that cannot keep the right way without a guide. Acknowledge and be affected with thine own weakness and emptiness, which thou mayst well be persuaded of.
