Terror accomplishes no real obedience. Suspense brings forth no fruit unto holiness. No gloomy uncertainty as to God's favor can subdue one lust, or correct our crookedness of will. But the free pardon of the cross uproots sin, and withers all its branches. Only the certainty of love, forgiving love, can do this.
Horatius Bonar, from God's Way of Holiness
