Yes, the spotted hyæna is a lovely animal. But they don't look like leopards.
Jesus is clear that He will be killing all our enemies, and there will be billions of them, when He returns. So vast a number as He has promised to kill necessarily includes many evil babies.
Revelation 6:7-8
Revelation 9:15-18
Isaiah also mentions animals sent by God to chomp heathens, babies are specifically mentioned. God would not send chomping animals to dismember good babies so we know that these babies were dealt with appropriately. It is likely that they would have grown up to be cannibals. Or something. Here are the animals mentioned:
- wild beasts of the desert
- doleful creatures
- owls
- satyrs
- wild beasts of the islands (these may have been hyænas)
- dragons
Isaiah 13:6-22
God knows just how every baby will turn out even from the moment of conception
Psalm 51:5 and sure enough every baby will be evil. Without Jesus to undo the damage done by Eve we would all be evil too. But having accepted God's Plan for our lives means that Christians are spared the hateful fact of unregenerate babies, infants, children, teenagers, men, women and geriatrics. Whether it's the past history of Genesis or the future history of Revelation or any other history in between we are assured that all these wretches will be dealt with by God because He hates them too.
It's quite a list.
