Thomas Boston, Works, 2:8:
Christ is made sanctification. There is a fulness of the spirit of holiness lodged in him, to be communicated to the unholy; and to him God sends the unholy sinner, that out of his fulness he may receive, and grace for grace. Therefore the most sober natural man and strictest professor, who has hammered out of his mere natural abilities, assisted by external revelation, a life blameless before the world, being estranged still to the life of faith, must know that he has but put a new face on the old man, which Christ never intended to repair, but to destroy, Rom. 6:6; and must begin anew to attain true holiness, from and by him whom the Father has made sanctification to us. And the most polluted sinner, whose lusts are most raging, may confidently try this grand method of sanctification, which can no more fail him than God’s device can fail to reach the end he designed for it.
