Justification is ‘inamissibilis;’ it is a fixed permanent thing, it can never be lost. The Arminians hold an apostasy from justification; today justified, tomorrow unjustified; today a Peter, tomorrow a Judas; today a member of Christ, tomorrow a limb of Satan. This [Arminian doctrine] is a most uncomfortable doctrine.
Justified persons may fall from degrees of grace, they may leave their first love, they may lose God’s favor for a time, but not lose their justification. If they are justified they are elected; and they can no more fall from their justification than from their election. If they are justified they have union with Christ; and can a member of Christ be broken off? If one justified person may fall away from Christ, all may; and so Christ would be a head without a body.
See from hence [this], that there is nothing within us that could justify but something without [outside] us; not any righteous inherent, but imputed. We may as well look for a star in the earth as for justification in our own righteousness. The Papists say we are justified by works; but the Apostle confutes it, for he says, ‘not of works, lest any man should boast.’ (Eph 2.9).
