Conversion is a work that most do not appreciate. It is not a small matter to transform an earthly, sin-loving mind and bring it to understand the unspeakable love of Christ, the charms of His grace, and the excellency of God, so that the soul shall be imbued with divine love and captivated with the heavenly mysteries. When he understands these things, his former life appears disgusting and hateful. He hates sin, and, breaking his heart before God, he embraces Christ as the life and joy of the soul. He renounces his former pleasures. He has a new mind, new affections, new interest, new will; his sorrows, and desires, and love are all new…. Heaven, which once possessed no charms, is now viewed in its riches and glory; and he contemplates it as his future home, where he shall see, love, and praise the One who hath redeemed him by His precious blood. The works of holiness, which appeared wearisome, are now his delight. The Word of God, which was dull and uninteresting, is now chosen as his study, the man of his counsel. It is as a letter written to him from God, bearing the inscription of the Eternal. His thoughts, his words, and his deeds are brought to this rule and tested. He trembles at the commands and threatenings which it contains, while he firmly grasps its promises and strengthens his soul by appropriating them to himself.
When the transforming grace of Christ is upon the heart, a righteous indignation will take possession of the soul because the sinner has so long neglected the great salvation that God has provided for him. He will then surrender himself, body, soul, and spirit, to God and will withdraw from companionship with Satan, through the grace given him of God.
All need to understand the process of conversion. The fruit is seen in the changed life.
