Westminster Confession of Faith
IX. Of Free-Will
4. When God converts a sinner, and translates him into the state of grace, He freeth him from his natural bondage under sin; and, by His grace alone, enables him freely to will and to do that which is spiritually good; yet so, that by reason of his remaining corruption, he doth not perfectly, nor only, will that which is good, but doth also will that which is evil.
X. Of Effectual Calling
1. All those whom God hath predestined unto life, and those only, He is pleased, in His appointed and accepted time, effectually to call, by His word and Spirit, out of that state of sin and death, in which they are by nature to grace and salvation, by Jesus Christ; enlightening their minds spiritually and savingly to understand the things of God, taking away their heart of stone, and giving unto them an heart of flesh; renewing their wills, and, by His almighty power, determining them to that which is good, and effectually drawing them to Jesus Christ: yet so, as they come most freely, being made willing by His grace.
XIII. Of Sanctification
1. They, who are once effectually called, and regenerated, having a new heart, and a new spirit created in them, are further sanctified, really and personally, through the virtue of Christ’s death and resurrection, by His Word and Spirit dwelling in them, the dominion of the whole body of sin is destroyed , and the several lusts thereof are more and more weakened and mortified; and they more and more quickened and strengthened in all saving graces, to the practice of true holiness, without which no man shall see the Lord.
XVI. Of Good Works
3. [Believers’] ability to do good works is not at all of themselves, but wholly from the Spirit of Christ. And that they may be enabled thereunto, beside the graces they have already received, there is required an actual influence of the same Holy Spirit to work in them to will, and to do, of His good pleasure: yet are they not hereupon to grow negligent, as if they were not bound to perform any duty unless upon a special motion of the Spirit; but they ought to be diligent in stirring up the grace of God that is in them.
The Larger Catechism
Q. 67. What is effectual calling?
A. Effectual calling is the work of God’s almighty power and grace, whereby (out of his free and special love to his elect, and from nothing in them moving him thereunto) he doth, in his accepted time, invite and draw them to Jesus Christ, by his word and Spirit; savingly enlightening their minds, renewing and powerfully determining their wills, so as they (although in themselves dead in sin) are hereby made willing and able freely to answer his call, and to accept and embrace the grace offered and conveyed therein.
