Romans 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. 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.
God's unbroken purpose is set out for those foreknown to be conformed to the image of His Son, moving from predestination to calling to justification to glorification. Calling is the Holy Spirit's work of drawing sinners to Christ, convicting them of sin and inviting them to repent, and justification follows that calling. The order shows that sinners do not produce repentance or make themselves fit for grace before coming to Christ, but the Spirit's drawing enables them to come to Christ and repent. Justification comes through belief in Jesus, and all who believe will be justified, and all whom God justifies will also be glorified.
When the sinner drawn by Christ's love approaches the cross and bows before it, he becomes a new creation with a new heart, a new creature in Christ of whom holiness has nothing more to require. The One who justifies and glorifies is the risen and ascended Saviour who entered heaven as the representative of His people, having redeemed them with His own blood, and who now pleads with the Father as their Advocate. Being counted righteous includes being made holy and glorious by a progressive work in this life, in which after receiving the truth the sinner strives for freedom from sin and, by beholding Christ, is changed into His image from one stage of glory to another, so that sanctifying power appears in thought, word, and deed. Because God gave His only Son to bear the penalty of transgression, He will also give all that is needed in the struggle against evil, so believers can even now have a foretaste of the perfect bliss awaiting the overcomer.
Final glorification means being raised from the grave just as Christ was raised from the dead and being lifted up to sit together with Him in heavenly places, with Christ as head, hope, and rejoicing, giving every reason to rejoice and sing praises. Glorification brings honor and exaltation through redeeming love that is greater than the shame and degradation of sin, and to human beings striving for conformity to the divine image God imparts heavenly treasure and excellency of power that will place redeemed sinners higher than even the angels who never fell. The verse belongs with the surrounding assurance for those who love God and are called according to His purpose, that the Spirit helps weakness in prayer with unutterable intercession according to the will of God, that all things work together for good to them, and that if God is for His people none can stand against them. This assurance applies to people who cannot save themselves, for Christ intercedes for them and through His atonement supplies moral strength so that even the weakest can overcome by divine grace. In the setting of Romans 8:28-36 the passage gives assurance to believers in terrible conflict that God's power works like fire in the burning bush, consuming the dross and refining the believer without consuming the person.
