...How many ways to make this point before Calvinists will accept ... this ...
They are willingly blind and deaf. They themselves refuse to see, as it is written:
Matthew 13:15 KJB - For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
Words that modify, or are conditions set forth by God, like "if", "abide", "continue", "otherwise", "cut off", "remain", "castaway", "was", "washed", "covered", "then", "shall", "until", all go unseen, and unheard. They see and hear what they desire, that they do not have to deal with their sins, that they presently do, for they do not even understand the simple definition of sin, as it is plainly given in 1 John 3:4 KJB, and because of this, their heart grows hard against the Holy Ghost Himself, who repoves of sin, righteousness and judgment [John 16:8 KJB], and so they flee from the questions He asks, unwilling to face the mirror [James 1:23 KJB], and the answer it so manifestly gives:
Hebrews 5:11 KJB - Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
Hebrews 5:12 KJB - For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat.
Paul, in Romans 8:38-39 KJB, clearly states that only one thing will separate us from God, and it is not external to us.
They will instead cling to their texts, which they themselves abuse, and wrest from their meaning [such as Hebrews 10:14 KJB, etc], unwilling to read the remaining context, which overthrows their self-important and sinful lifestyle. They deceive only themselves. Scripture, is clear, they are what they are, 1 John 2:4 KJB, though they profess otherwise, but what proceeeds from their mouth, stems from their father, John 8:44 KJB, for out of their heart, their mouth speaketh, shewing that they are the children of another, Matthew 13:18 KJB. They, like, the professed atheist, who says that they have never had evidence for God's existence, in which Romans 1 declares by the Holy Ghost, that they have had such evidence, even all around them, why then do men believe their words, over and above what God already declared them to be? I refuse their lies. I accept God's judgment of them. They will perish if they do not repent, and their refuge of lies will not save them:
Isaiah 28:17 KJB - Judgment also will I lay to the line, and righteousness to the plummet: and the hail shall sweep away the refuge of lies, and the waters shall overflow the hiding place.
They have not hold of the New Covenant, but they hold the covenant of hell and death [Romans 6:23 KJB], which shall be utterly disannulled:
Isaiah 28:15 KJB - Because ye have said, We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves:
Isaiah 28:18 KJB - And your covenant with death shall be disannulled, and your agreement with hell shall not stand; when the overflowing scourge shall pass through, then ye shall be trodden down by it.
They refuse to humble themselves before God, and to admit their errors - so be it. Woe unto you Chorazin. Woe unto you Bethsaida. Woe unto you Sodoma and Gomorrah:
Amos 5:18 KJB - Woe unto you that desire the day of the LORD! to what end is it for you? the day of the LORD is darkness, and not light.
