The Fifth Head of Doctrine: The Perseverance of the Saints
Article 13: Assurance No Inducement to Carelessness
Neither does the renewed confidence of perseverance produce immorality or lack of concern for godliness in those put back on their feet after a fall, but it produces a much greater concern to observe carefully the ways of the Lord which he prepared in advance. They observe these ways in order that by walking in them they may maintain the assurance of their perseverance, lest, by their abuse of his fatherly goodness, the face of the gracious God (for the godly, looking upon his face is sweeter than life, but its withdrawal is more bitter than death) turn away from them again, with the result that they fall into greater anguish of spirit.
Article 14: God’s Use of Means in Perseverance
And, just as it has pleased God to begin this work of grace in us by the proclamation of the gospel, so he preserves, continues, and completes his work by the hearing and reading of the gospel, by meditation on it, by its exhortations, threats, and promises, and also by the use of the sacraments.
