Westminster Confession 8.8

westminster2If I told you that someone was very good at their job what would you understand that to mean?  You would likely understand me to mean that the things they set out to do in their work they usually accomplish.  But you would almost certainly not understand me to be saying that EVERYTHING they set out to in their work they accomplish…you would not imagine them to be successful 100% of the time.
Now this is our human  experience, but we would be wrong to think similarly about Christ.  He doesn’t set out to save a people from their sins and bring them to glory only to get say 85% of them.  We don’t admire Jesus for being very good at what he does in saving sinners because he succeeds 85% of the time and fails 15% of the time or at least we ought not to.
The Reformers saw in the Scriptures that the Lord Jesus was given an elect people by his Father and that it was his job to save 100% of them and to do so completely, to bring them all they way from condemnation to glory.  We read of this in 8.1.  It was the eternal decree of the Father that Christ should be the mediator between God and man AND that  he be given a people to be by him redeemed, called, justified, sanctified, and glorified. (Ephesians 1, John 17 etc.)  We also read in 8.5 that the Lord Jesus in his obedience and death fully satisfied the justice of God and purchased an eternal inheritance for those God had given him.
Now in 8.5 we read that Christ will make sure that all those that were chosen for salvation in him and for him he purchased that Salvation in his obedience and death will actually receive it.  He doesn’t just bring his elect part way and hope that most of them make it.  He continues to work as mediator; prophet, priest, and King in order that every single one of those give to him is brought fully to eternal glory.
As living priest he makes intercession for his people, praying for them and ensuring that every blessing the need is given to them.
As living prophet he reveals to them in and by the Word they mysteries of salvation and effectually persuades them by his Spirit to believe and obey.
And as living King he governs their hearts by his Word and Spirit and overcomes all their enemies by his almighty power and wisdom.
The point of the biblical and confessional teaching at this point is not to explore the ins and outs of election and effectual calling.  It is rather to point us to the greatness of our living and active Savior.
He is very good at what he does!!!
Westminster Confession 8.8
VIII. To all those for whom Christ has purchased redemption, He does certainly and effectually apply and communicate the same;[39] making intercession for them,[40] and revealing unto them, in and by the word, the mysteries of salvation;[41] effectually persuading them by His Spirit to believe and obey, and governing their hearts by His word and Spirit;[42] overcoming all their enemies by His almighty power and wisdom, in such manner, and ways, as are most consonant to His wonderful and unsearchable dispensation.[43]
Scripture:

[39] JOH 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. 39 And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 10:15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. 16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.

[40] 1JO 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: 2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. ROM 8:34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.

[41] JOH 15:13 Greater love hath no man than this, that a man lay down his life for his friends. 15 Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you. EPH 1:7 In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace; 8 Wherein he hath abounded toward us in all wisdom and prudence; 9 Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself. JOH 17:6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word.

[42] JOH 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever. HEB 12:2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. 2CO 4:13 We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak. ROM 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his. 14 For as many as are led by the Spirit of God, they are the sons of God. 15:18 For I will not dare to speak of any of those things which Christ hath not wrought by me, to make the Gentiles obedient, by word and deed, 19 Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and round about unto Illyricum, I have fully preached the gospel of Christ. JOH 17:17 Sanctify them through thy truth: thy word is truth.

[43] PSA 110:1 The Lord said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool. 1CO 15:25 For he must reign, till he hath put all enemies under his feet. 26 The last enemy that shall be destroyed is death. MAL 4:2 But unto you that fear my name shall the Sun of righteousness arise with healing in his wings; and ye shall go forth, and grow up as calves of the stall. 3 And ye shall tread down the wicked; for they shall be ashes under the soles of your feet in the day that I shall do this, saith the Lord of hosts. COL 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
