Indefectibility

"In all ages this doctrine of the final perseverance of the saints has been opposed and denied. Satan himself believed in the apostasy of Job and had the effrontery to avow it unto Jehovah ( Job 1:8-11). We need not be surprised then to find that the supreme imposture of the religious realm repudiates most vehemently this precious truth and pronounces accursed all who hold it. The merit-mongers of Rome are inveterately opposed to everything which exalts free grace. Moreover, they who so hotly deny unconditional election, particular redemption, and effectual calling, must, in order to be consistent, deny the eternal security of the Christian. Since Papists are such rabid sticklers for the “free will” of fallen man, logically, they must deny the indefectibility of all who are in Christ. If I have by an act of my own volition brought myself into a state of grace, then it clearly follows that I am capable of forsaking the same. If the “free will” of the sinner first inclines him to exercise repentance and faith, then obviously he may relapse into a state of confirmed impenitence and unbelief." —A. W. Pink (1886–1952)
