The Cross and Salvation p. 35
One strand of Reformed thinking holds that, subjectively, the Spiriti enables the chosen and called to believe th truth in Christ, turn from all known sins, and trust Jesus as Savior and Lord of their lives. God creates in the converted a new spiritual nature – in the sense not of another ontological constitution but as a new set of godly inclinations, desires, and habits. Objectively, the Spirit incorporates regenerated believers into Christ in a vital, spiritual, and indissoluble union, attested by the common “in Christ” motif. The Father then forgives their sins, accepts them as righteous in his sight, and bestows the gift of eternal life. Furthermore, in the lifelong work of sanctification the Spirit progressively mortifies believers’ old nature and fortifies the new nature such that they become like Jesus in thought, word, and deed. Thus God not only declares believing sinners righteous; he effectively makes them so by the Spirit. We are saved not merely to gain heaven but also to live in holiness, truth, and love. Moreover, those whom God has regenerated, united to Christ, and justified he preserves by the Spirit to the end. Twice-born people at times disobey God and grieve his Spirit; but the Lord’s sure grip prevents them from falling away finally and completely. Lastly, God will bring salvation to completion at the return of Christ when pilgrim saints behold the Savior’s face and are fully transformed into his likeness. Biblical salvation thus has past, present, and future dimensions. The born-again person can say with confidence, “I have been saved, I am being saved, and at Christ’s return I finally will be saved.”
That last line is epic.
