According to Calvinism, God takes pleasure in tormenting people for all eternity with hellfire because it gives Him glory.
I've never seen or heard of a "Calvinist" who teaches this, though there may be some I'm not aware of who do or did.
According to other theological systems, God hates having to do this because the very people whom He in His justice must punish with eternal hellfire, for their refusal to believe on Christ, are people that He loves.
Yes, I have indeed heard this preached from pulpits, on radio and on television, as well as having seen it in print... for decades.
I'm also aware that this, or something very much like it, has been preached by
many now for literally centuries.
Does God delight in burning people in Hell?
No ( Ezekiel 18:23, Ezekiel 33:11 ).
That said, If you will permit a question from me...
According to what
the Scriptures teach ( not men ), does God love
anyone that He sends to Hell (and from there, to eternal punishment in the Lake of Fire)?
For reference, please see Psalms 5, Psalms 9, Psalms 10, Psalms 11, Psalms 14, Proverbs 15:29, John 9:31 and many, many others... and then ( and this is my hope )
carefully compare and contrast what is said in those to what is said in John 3.
