For true conversion doth not consist in putting away great and outward sins only, but in descending deeply into your own self, searching into the inmost recesses of the heart, the secrets and closets, all the windings and turnings thereof; changing and renewing them throughout, with the grace that is given you: and so, by faith, you are converted from self-love to Divine love; from the world and all worldly concupiscences, to a spiritual and heavenly life; and from a participation of the pomps and pleasures thereof, to participating the merits and virtues of Christ, by believing his word, and walking in his steps.
