Article 3. By reason of these remains of indwelling sin, and the temptations of sin and of the world, those who are converted could not persevere in a state of grace, if left to their own strength. But God is faithful, who having conferred grace, mercifully confirms, and powerfully preserves them herein, even to the end.
Article 4. Although the weakness of the flesh cannot prevail against the power of God, who confirms and preserves true believers in a state of grace, yet converts are not always so influenced and actuated by the Spirit of God, as not in some particular instances sinfully to deviate from the guidance of divine grace, so as to be seduced by, and to comply with the lusts of the flesh; they must, therefore, be constant in watching and in prayer, that they be not led into temptation. When these are neglected, they are not only liable to be drawn into great and heinous sins, by Satan, the world and the flesh, but sometimes by the righteous permission of God actually fall into these evils. This, the lamentable fall of David, Peter, and other saints described in Holy Scripture, demonstrates.
Article 5. By such enormous sins, however, they very highly offend God, incur a deadly guilt, grieve the Holy Spirit, interrupt the exercise of faith, very grievously wound their consciences, and sometimes lose the sense of God’s favor, for a time, until on their returning into the right way of serious repentance, the light of God’s fatherly countenance again shines upon them.
Article 6. But God, who is rich in mercy, according to his unchangeable purpose of election, does not wholly withdraw the Holy Spirit from his own people, even in their melancholy falls; nor suffers them to proceed so far as to lose the grace of adoption, and forfeit the state of justification, or to commit sins unto death; nor does he permit them to be totally deserted, and to plunge themselves into everlasting destruction.
Article 7. For in the first place, in these falls he preserves them in the incorruptible seed of regeneration from perishing, or being totally lost; and again, by his Word and Spirit, certainly and effectually renews them to repentance, to a sincere and godly sorrow for their sins, that they may seek and obtain remission in the blood of the Mediator, may again experience the favor of a reconciled God, through faith adore his mercies, and henceforward more diligently work out their own salvation with fear and trembling.
Article 8. Thus, it is not in consequence of their own merits, or strength, but of God’s free mercy, that they do not totally fall from faith and grace, nor continue and perish finally in their backslidings; which, with respect to themselves, is not only possible, but would undoubtedly happen; but with respect to God, it is utterly impossible, since his counsel cannot be changed, nor his promise fail, neither can the call according to his purpose be revoked, nor the merit, intercession and preservation of Christ be rendered ineffectual, nor the sealing of the Holy Spirit be frustrated or obliterated.
Article 9. Of this preservation of the elect to salvation, and of their perseverance in the faith, true believers for themselves may and ought to obtain assurance according to the measure of their faith, whereby they arrive at the certain persuasion, that they ever will continue true and living members of the church; and that they experience forgiveness of sins, and will at last inherit eternal life.
