A.W. Pink (The Sovereignty of God)

The new birth is very, very much more than simply shedding a few tears due to a temporary remorse over sin. It is far more than changing our course of life, the leaving off of bad habits and the substituting of good ones. It is something different from the mere cherishing and practising of noble ideals. It goes infinitely deeper than coming forward to take some popular evangelist by the hand, signing a pledge-card, or “joining the church.” The new birth is no mere turning over a new leaf but is the inception and reception of a new life. It is no mere reformation but a complete transformation. In short, the new birth is a miracle, the result of the supernatural operation of God. It is radical, revolutionary, lasting.

Here then is the first thing, in time, which God does in His own elect. He lays hold of those who are spiritually dead and quickens them into newness of life. He takes up one who was shapen in iniquity and conceived in sin, and conforms him to the image of His Son. He seizes a captive of the Devil and makes him a member of the household of faith. He picks up a beggar and makes him joint-heir with Christ. He comes to one who is full of enmity against Him and gives him a new heart that is full of love for Him. He stoops to one who by nature is a rebel and works in him both to will and to do of His own good pleasure. By His irresistible power He transforms a sinner into a saint, an enemy into a friend, a slave of the Devil into a child of God.
