Sanctification is that continuous operation of the Holy Spirit, by which the holy disposition imparted in regeneration is maintained and strengthened. Godet: “The work of Jesus in the world is twofold. It is a work accomplished _for us_, destined to effect _reconciliation_ between God and man; it is a work accomplished _in us_, with the object of effecting our _sanctification_. By the one, a right _relation_ is established between God and us; by the other, the _fruit_ of the reëstablished order is secured. By the former, the condemned sinner is received into the state of grace; by the latter, the pardoned sinner is associated with the life of God.... How many express themselves as if, when forgiveness with the peace which it procures has been once obtained, all is finished and the work of salvation is complete! They seem to have no suspicion that salvation consists in the health of the soul, and that the health of the soul consists in holiness. Forgiveness is not the reëstablishment of health; it is the crisis of convalescence. If God thinks fit to declare the sinner righteous, it is in order that he may by that means restore him to holiness.” O. P. Gifford: “The steamship whose machinery is broken may be brought into port and made fast to the dock. She is _safe_, but not _sound_. Repairs may last a long time. Christ designs to make us both safe and sound. Justification gives the first—safety; sanctification gives the second—soundness.” Bradford, Heredity and Christian Problems, 220—“To be conscious that one is forgiven, and yet that at the same time he is so polluted that he cannot beget a child without handing on to that child a nature which will be as bad as if his father had never been forgiven, is not salvation in any _real_ sense.” We would say: Is not salvation in any _complete_ sense. Justification needs sanctification to follow it. Man needs God to continue and preserve his spiritual life, just as much as he needed God to begin it at the first. Creation in the spiritual, as well as in the natural world, needs to be supplemented by preservation; see quotation from Jonathan Edwards, in Allen’s biography of him, 371. Regeneration is instantaneous, but sanctification takes time. The “developing” of the photographer’s picture may illustrate God’s process of sanctifying the regenerate soul. But it is development by new access of truth or light, while the photographer’s picture is usually developed in the dark. This development cannot be accomplished in a moment. “We try in our religious lives to practise instantaneous photography. One minute for prayer will give us a vision of God, and we think that is enough. Our pictures are poor because our negatives are weak. We do not give God a long enough sitting to get a good likeness.”
