There must be a constant and increasing appreciation that though sin still remains it does not have the mastery. There is a total difference between surviving sin and reigning sin, the regenerate in conflict with sin and the unregenerate complacent to sin. It is one thing for sin to live in us: it is another for us to live in sin. It is of paramount concern for the Christian and for the interests of his sanctification that he should know that sin does not have the dominion over him, that the forces of redeeming, regenerative, and sanctifying grace have been brought to bear upon him in that which is central in his moral and spiritual being, that he is the habitation of God through the Spirit, and that Christ has been formed in him the hope of glory.
