Jerry Walls The issue here is what would perfect love do if faced with the scenario of the three children. It's very telling that Calvinists always cast the issue as one of justice rather than love. Moreover, if the atonement is understood as Calvinists often do, in terms of penal substitution...
i) We cast it in those terms because that's how Scripture casts it. Even when Scripture speaks of God's love, it's using love as a synonym for God's mercy or pity or grace. God's love for sinners rather than creatures. It's a mercy/justice dialectic.
ii) It's striking that he comes out of the closet as an opponent of penal substitution. Walls has quite a following among Arminians. Yet many modern-day Arminians espouse penal substitute. Yet to judge by this comment, Walls regards penal substitution as a part of the Calvinist package rather than the Arminian package.
iii) Since Walls is not a universalist, how does he justify eschatological punishment if divine love trumps divine justice? I don't know if he espouses annihilationism or everlasting hell. But in either event, that's retributive rather than remedial.
Scripture definitely treats eschatological judgment as punitive: just deserts. Comeuppance.
By process of elimination, he's committed to retributive punishment. There are three basic options: deterrence, retribution, or remediation.
Postmortem punishment can't be for deterrence. Too late for that. And since he's not a universalist, it can't be for remediation.
It's possible that given his belief in postmortem salvation, he'd include remedial punishment to motivate postmortem conversion. Mind you, that's coercive, so that collides with his commitment to libertarian freedom.
But even if he thinks postmortem punishment has some remedial benefit, he doesn't believe all dead unbelievers will be responsive to God's postmortem overtures. So he must still fall back on retribution for that recalcitrant subset.
But if love is God's primary attribute, then why does God punish anyone for not believing in him or reciprocating his love? Assuming (arguendo) that he can't make them love him or trust him, how are punitive measures the alternative to salvation?
Why not make the lost as comfortable as possible? Why not continuously treat unbelievers better than they deserve?
Given Walls's theological assumptions, eschatological punishment seems petty and vindictive.
