"Not only does the Lord through forgiveness of sins receive and adopt us once for all into the church, but through the same means he preserves and protects us there. For what would be the point of providing a pardon for us that was destined to be of no use? . . . We must firmly believe that by God's generosity, mediated by Christ's merit, through the sanctification of the Spirit, sins have been and are daily pardoned to us who have been received and engrafted into the body of the church."
Calvin, Institutes, 4.1.21.
