Whilst there abides a treachery in the heart to indulge to any negligence in not pressing universally to all perfection in obedience, the soul is weak, as not giving faith its whole work; and selfish, as considering more the trouble of sin that the filth and guilt of it; and lives under a constant provocation of God: so that it may not expect any comfortable issue in any spiritual duty that it doth undertake, much less in this under consideration, which requires another principle and frame of spirit for its accomplishment.
