I'll tell you.
The passage says believers, that is, people SANCTIFIED BY THE BLOOD OF CHRIST will be condemned with the enemies of God if they trample on the blood of Christ, and insult the Spirit of grace (charis-the favor of gifting), through a conscious, willful continuing in sin (that lifestyle of sin John talks about).
No it doesn't say that at all.
First, we know that eternal life is a gift of God and God's gifts are irrevocable. And Paul NEVER excluded the gift of eternal life from the gifts that are irrevocable. And no one has shown otherwise.
Second, the aorist tense in a number of verses totally refutes the theory that one must continue to believe in order to stay saved. In John 4:14, 6:51, 53, 54 Jesus used the aorist tense when He used the euphemisms of eating and drinking Him for belief in Him. But don't take my word for it. Here are His actual words:
Jn 4:14 - but whoever drinks (aorist) of the water that I will give him shall never thirst; but the water that I will give him will become in him a well of water
springing up to eternal life.”
Jn 6:51 - “I am the living bread that came down out of heaven; if anyone eats (aorist) of this bread,
he will live forever; and the bread also which I will give for the life of the world is My flesh.”
Jn 6:53, 54 - So Jesus said to them, “Truly, truly, I say to you, unless you eat (aorist) the flesh of the Son of Man and drink (aorist) His blood, you have no life in yourselves. 54“He who eats (aorist) My flesh and drinks (aorist) My blood
has eternal life, and I will r
aise him up on the last day. This is a promise of eternal life from a point in time action.
These are guarantees from Jesus Himself about living forever as a result of an action in a point in time (aorist).
If one must continue to believe in order to continue to have eternal life, then the Bible would
NEVER HAVE USED THE AORIST TENSE.
And even Paul used the aorist tense in his answer to the jailer: They said, “Believe (aorist) in the Lord Jesus, and you will be saved, you and your household.” Acts 16:31
"26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a terrifying expectation of judgment and THE FURY OF A FIRE WHICH WILL CONSUME THE ADVERSARIES. 28 Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses. 29 How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted 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." (Hebrews 10:26-30 NASB capitals in original)
This is about divine discipline.
This passage has been attacked from every angle (i.e. they aren't really believers, the punishment isn't really hell, yada, yada, yada) and has survived every one of them.
In fact, it is the anti-eternal security view that has been thoroughly refuted directly from Scripture.
Because this and other passages are in the Bible it's impossible that the gifts that are irrevocable in Romans 11:29 NASB includes redemption, the forgiveness of our sins. Impossible.
So then your view must conclude that Paul was dead wrong
[just end the statement here. ToS 2.4]. That is what is impossible. No where has anyone shown that Paul's idea of "gifts" in Rom 11:29 was anything other than what he already had defined as gifts in 1:11 (spiritual gifts), justification in 3:24, 5:15,16,17, and eternal life in 6:23.
Unless, one wants to go on record that the Bible has a glaring contradiction in it.
Your view simply denies what is clearly taught.
