The Westminster Confession of Faith chapter 3:
VI. As God has appointed the elect unto glory, so has He, by the eternal and most free purpose of His will, foreordained all the means thereunto.
[12] Wherefore, they who are elected, being fallen in Adam, are redeemed by Christ,
[13] are effectually called unto faith in Christ by His Spirit working in due season, are justified, adopted, sanctified,
[14] and kept by His power, through faith, unto salvation.
[15] Neither are any other redeemed by Christ, effectually called, justified, adopted, sanctified, and saved, but the elect only.
[16]
[12] 1PE 1:2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied. EPH 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will. 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. 2TH 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.
[13] 1TH 5:9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, 10 Who died for us, that, whether we wake or sleep, we should live together with him. TIT 2:14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
[14] ROM 8:30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. EPH 1:5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will. 2TH 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.
[15] 1PE 1:5 Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
[16] JOH 17:9 I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine. ROM 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose. JOH 6:64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. 65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father. 10:26 But ye believe not, because ye are not of my sheep, as I said unto you. 8:47 He that is of God heareth God's words: ye therefore hear them not, because ye are not of God. 1JO 2:19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.
