Westminster Confession Of Faith – Lord’s Day 27
Chapter 17 – Of The Perseverance of the Saints
I. They whom God has accepted in his Beloved, effectually called and sanctified by his Spirit, can neither totally nor finally fall away from the state of grace; but shall certainly persevere therein to the end, and be eternally saved.
II. This perseverance of the saints depends, not upon their own free-will, but upon the immutability of the decree of election, flowing from the free and unchangeable love of God the Father; upon the efficacy of the merit and intercession of Jesus Christ; the abiding of the Spirit and of the seed of God within them; and the nature of the covenant of grace; from all which arises also the certainty and infallibility thereof.
III. Nevertheless they may, through the temptations of Satan and of the world, the prevalence of corruption remaining in them, and the neglect of the means of their perseverance, fall into grievous sins; and for a time continue therein: whereby they incur God’s displeasure, and grieve his Holy Spirit; come to be deprived of some measure of their graces and comforts; have their hearts hardened, and their consciences wounded; hurt and scandalise others, and bring temporal judgments upon themselves.
