I read the article and said, boy this sounds awfully Calvinist. Then I looked up RC and discovered he is a Calvinist. Makes more sense now.
The author Mr. Ferguson’s argument, that he has 100% assurance of salvation seems to revolve around Hebrews 10:18-22 as proof of his assurance of salvation. If he would just keep reading…
26 For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. 28 A man who has violated the law of Moses dies without mercy at the testimony of two or three witnesses. 29 How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace? 30 For we know him who said, “Vengeance is mine, I will repay.” And again, “The Lord will judge his people.” 31 It is a fearful thing to fall into the hands of the living God.
I’m sure a person with full assurance of salvation would claim they have this assurance because of their “knowledge of the truth”. Well my question would be how can they have full assurance that they might not deliberately sin 20 years from now? Verse 26 makes it crystal clear that Jesus sacrifice will no longer remain, if they deliberately sin. Perseverance to the end is the key. Only God foreknows who will persevere, to claim you have 100% assurance of salvation is to claim you know what God knows.
35 Therefore do not throw away your confidence, which has a great reward.
Why would a person with 100% assurance need a warning to not throw away their confidence?
36 For you have need of endurance, so that you may do the will of God and receive what is promised.
If we don’t endure and do the will of God do we still have 100% assurance that will we still receive what is promised?
38 but my righteous one shall live by faith,
and if he shrinks back,
my soul has no pleasure in him.”
Yet another warning, if he shrinks back, how can anyone have 100% assurance that a tragic event in their life might not make them shrink back and deny Jesus Christ.
Sorry Mr. Ferguson you need to read all of Hebrews 10, in context, and not just pull out the verses that fits your theology.
