A verse regarding Judas:

“While I was with them, I was keeping them in Your name which You have given Me; and I guarded them and not one of them perished but the son of perdition, so that the Scripture would be fulfilled.” (John 17:12)

Destruction is not the End

God can call back men whom He sent for Destruction (in principle), verse below too:

“Thou turnest man to destruction; and sayest, Return, ye children of men.” (Psalm 90:3)

Also, Christ’s last words to Judas records Him calling Judas ‘His friend/comrade’ (Matthew 26:50) & Jesus laid down His life for ‘His friends’ (John 15:13)

The ‘enemy’ state for the sake of the Gospel is ‘temporal’ but these ‘same’ (Israelite examples) are still ‘beloved’ on account of patriarchs as apostle Paul explains in Romans 11:28 & thus implies that ‘all Israel will be saved’ (not just nationalistically but spiritually as all their sins are removed too, discussed in previous posts in detail) as written a ‘secret/Mystery’ Romans 11:26

Thus the calling of Judas as ‘Satan’ (briefly, temporal) but still called ‘His friend’ (permanent, in the end, final word) agrees with apostle Paul’s Revelation of the mystery discussed above too.

The ‘permanent’ “calling” of God —> that these enemies are still “beloved” (Romans 11:28) —> and the “gift” of “All Israel will be saved” including them (Romans 11:26) are “irrevocable” as apostle Paul explains the reason behind this after quoting all the above points first (‘context’ pertaining to the ‘topic’ in discussion)

“for the gifts and the calling of God are irrevocable.” (Romans 11:29)

The ‘temporal’ grafting in vs being cut off state were discussed earlier in this chapter too (Romans 11) as a necessary Judgment means toward this ‘end’ that “All Israel will be saved” & not an end in themselves as commonly erred when this Mystery or Secret is ignored as it’s mentioned in Romans 11:26 too!

*Judas being an Israelite, all the verses above (context) applies to him as well.

**Some scholars mention that the root Greek words for “perished or destroyed” and “lost” are very closely linked etymologically.

Regarding Christ (Who has “no” time-space nor any other limits to His Saving Power):

“For the Son of Man has come to seek and to save that which was lost.” (Luke 19:10)
