Going to sound strange but I think we should be praying for mercy for our enemies...
✝️ Scripture 🕊️
God will win and His might is beyond what we can imagine. Those that are the enemy of God will suffer enormous loss. Pray for God to have mercy on even those that are against Him.
Remember we were all against Him before He came looking for us and found us.
This would imply that there are limits on the infinite love and mercy of God. As bad as ritual human sacrifice is, it pales in comparison to Jesus Christ, the son of God, being murdered on the cross. And if God can forgive humanity for this abominable crime, then he can even forgive luciferians who sincerely repent of their sins.
They should definitely 100% receive the death penalty from an earthly judge because in justice that is what they deserve. But as far as before the tribunal of God, we should pray that they turn around from their evil and repent.
And what is the unpardonable sin? To blaspheme the HS? That's just the refusal to repent. Careful how you mete out vengeance because that is how it will be meted back to you.
If blasphemy against the HS is to spill innocent then the Crucifixion is the unpardonable and so no forgiveness would be possible.
