Growth in grace is not progressive sanctification and fleshly holiness on the one hand, nor a false and delusive establishment on the other. The narrow path lies between these two extremes. On the one side is Seneh, and on the other side is Bozez (1 Sam. 14:4), Pharisaic holiness and Antinomian security; and between these two sharp rocks lies the "path which no fowl knoweth, and which the vulture's eye hath not seen." From dashing on either of these rocks a living man is kept only by the mysterious dealings of God with his spirit, and the internal exercises through which he continually passes.
A constant acquaintance with his own vileness preserves him from a self-righteous holiness in the flesh; a daily cross and a rankling thorn keep him from careless presumption. His path is indeed a mysterious one, full of harmonious contradictions and heavenly paradoxes. He is never easy when at ease, nor without a burden when he has none. He is never satisfied without doing something, and yet is never satisfied with anything that he does. He is never so strong as when he sits still, never so fruitful as when he does nothing, and never so active as when he makes the least haste. All outstrip him in the race, yet he alone gains the goal, and wins the prize. All are sure of heaven but himself, yet he enters into the kingdom, whilst they are thrust out. He wins pardon through guilt, hope through despair, deliverance through temptation, comfort through affliction, and a robe of righteousness through filthy rags. Though a worm and no man, he overcomes Omnipotence itself through violence; and though less than vanity and nothing, he takes heaven itself by force.
Thus amidst the strange contradictions which meet in a believing heart, he is never so prayerful as when he says nothing; never so wise as when he is the greatest fool; never so much alone as when most in company; and never so much under the power of an inward religion as when most separated from an outward one.
