It has been said that no great work in literature or in science was ever wrought by a man who did not love solitude. We may lay it down as an elemental principle of religion, that no large growth in holiness was ever gained by one who did not take time to be often long alone with God.

Sanctification is that inward spiritual work which the Lord Jesus Christ works in a man by the Holy Ghost, when He calls him to be a true believer. He not only washes him from his sins in His own blood, but He also separates him from his natural love of sin and the world, puts a new principle in his heart, and makes him practically godly in life. The instrument by which the Spirit effects this work is generally the Word of God, though He sometimes uses afflictions and providential visitations “without the Word” (1 Peter 3:1). The subject of this work of Christ by His Spirit is called in Scripture a “sanctified” man.
