God's regenerating power is greater than the strength of the world, hell, or man's wicked heart; he can draw the worst sinners to Christ.The Zealous Christian
In a multitude of cases, and in all cases where regeneration is spoken of, it means the whole soul; that is, it includes the intellect, will, and the conscience as well as the affections. Hence the Bible speaks of the eyes, of the thoughts, of the purposes, of the devices, as well as of the feelings or affections of the heart. In Scriptural language, therefore, a 'new heart' does not mean simply a new state of feeling, but a radical change in the state of the whole soul or interior man.
Regeneration is birth; sanctification is growth. In regeneration, God implants desires that were not there before: desire for God, for holiness, and for the hallowing and glorifying of God's name in this world;Concise Theology
Regeneration was a momentary monergistic act of quickening the spiritually dead. As such, it was God's work alone. Sanctification, however, is in one sense synergistic -it is an ongoing, cooperative process in which regenerate persons, alive to God and freed from sin's dominion (Rom. 6:11, 14-18), are required to exert themselves in sustained obedience.Concise Theology
He can make the dry parched ground of my soul to become a pool and my thirsty barren heart as springs of water. Yes he can make this habitation of dragons this heart which is so full of abominable lusts and fiery temptations to be a place of bounty and fruitfulness unto Himself
