The promises of sanctifying grace are available to believers now, or they are worthless. For true faith can be exercised for spiritual grace for ourselves only as it rests on the promise which includes the present moment. "Knowing this, that the body of sin might be destroyed, that henceforth we should not serve sin." This promise of the destruction of sin begins now, and is followed by a glorious henceforth of emancipation this side of death.
Let the reader study the following promises, and observe how manifestly they imply present fulfillment: Isa. 1:18, 25; Titus 2:14; 1 John 1:9; 4:16-18. Let him also remember that every command to be holy covers the present, and contains an implied promise of the aid of the Sanctifier.
