3 To him the doorkeeper opens, and the sheep hear his voice, and he calls his own sheep by name and leads them out. 4 When he puts forth all his own, he goes ahead of them, and the sheep follow him because they know his voice. John 10:3-4 (NASB)
WESTMINSTER CONFESSION OF FAITH CHAPTER X
Of Effectual Calling
All those whom God hath predestinated unto life, and those only, He is pleased, in His appointed 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.
