Yes!(Matt. 16:16-17) In 'Boxcar" letters! And Peter was no more saved then (and no more nor no less saved) than he was when Jesus called him "Satan," and said Peter was "an offense" to Himself, a mere seven verses later when Peter argued that the Lord Jesus should not die and be raised the third day. (Talk about "crossless!") (Matt. 16:22-23)
And I will use "born again", "regenerate" and "saved", interchangeably, and ask about these individuals.
Was David saved when he was both a murderer and an adulterer? (II Sam. 11:24; Ps.51)
Was Rahab saved when she was a prostitute? (Jas. 2:25)
Was Samson saved when he was one of the notorious 'womanizers' in history? (Jdg. 14:7; 16:1)
Was Noah saved when he was drunk? (Gen. 9:20-24)
Was Jacob saved when he was the biggest 'cheat' and/or swindler in the Bible? (Gen. 27:36; 30; 31)
Was Gideon saved when he was one of the biggest cowards of all time, scared of his own shadow, his neighbors, and even his own father, and who argued with the LORD that he was too weak to do anything, and even had to have his father protect him, after the little vandalism incident of casting down the altar of Baal, that actually belonged to his father? (Jdg. 6)
Was Solomon saved when he was the greatest 'polygamist' in history (Compared to Solomon, the Eldorado bunch, are at best, fifth rate 'wannabes'!), with personal wealth that would make Midas look like a pauper, and with more wives than all the other kings in the line of the Lord Jesus of Israel and Judah combined, which was in direct disobedience to God's direct prohibition for a king to 'multiply' wives (and wealth) for himself? (Deut. 17:17, I Ki. 11:3)
Was Jonah saved when he was the most obnoxious bigot in Scripture, who did not want anyone to heed his message, instead wanting God to destroy Ninevah, where he preached a message of fewer than 10 words, from a street corner, effectively told the LORD, "Okay! I preached what you asked.", and was angry with GOd, when He did not destroy Ninevah, because they repented, said he'd rather be dead than to have to live with that crowd? [Jonah seemed to forget that he had already been physically dead, once before ('Living' people were not found in Sheol, the realm of the dead.) and he didn't like it, but still he was willing to be dead again, in order to keep down the 'population explosion' of 'undesirables' in Paradise, even if they were now among the 'redeemed'.] (Jon. 3:4-4:12)
These are just a few from the OT. Let's ask about a couple of folks you may have heard of in the NT.
Was Thomas saved when he "doubted" in that he refused to believe the testimony of 10 apostles who were eyewitnesses that Jesus had been raised from the dead, and said that unless he, personally, could jab his hand into Jesus' side, "Iwill not believe!", the most notorious 'skeptic' in the Bible? (Jn. 20:25)
Was Paul saved when he said he "am'chief' of sinners?" You do notice that Paul did not say he once was chief of sinners, I presume! (I Tim. 1:15)
And one more from the OT: Was that great 'role model', paragon of virtue, and whom I call the Biblical "saint of saints", because he is one of only two, or perhaps three individuals whom the Bible calls "righteous" or "just" three different times (and the only individual in Scripture specifically identified as being among "the godly") - "Yep! You got it!" - 'Hizzoner', himself, Ol' Lot, saved when he was the Mayor of Sodom? (Gen. 19:1; II Pet. 2:7)
Yes, they were all saved. -all 11 of 'em, as well, according to what I read. The first 6 are even found in what is described as the "Hall of Fame of faith" chapter in Scripture - Heb. 11.
The way I got it figured, including Peter, that's a Christ-denier, a murderer and an adulterer, to boot, a hooker, a womanizer, a swindler, a drunk, a coward, a polygamist, a bigot, a skeptic, the chief of sinners, and the Mayor of Sodom.
Hey, Nice Crowd!
Incidentally, I challenge anyone to show me where the Bible ever says any of them 'repented'. Of or from anything!
