Isaiah 11:6-9
The wolf shall dwell with the lamb: and the leopard shall lie down with the kid: the calf and the lion, and the sheep shall abide together, and a little child shall lead them.The calf and the bear shall feed: their young ones shall rest together: and the lion shall eat straw like the ox. And the sucking child shall play on the hole of the asp: and the weaned child shall thrust his hand into the den of the basilisk. They shall not hurt, nor shall they kill in all my holy mountain, for the earth is filled with the knowledge of the Lord, as the covering waters of the sea.
1 Corinthians 2:9
But, as it is written: That eye hath not seen, nor ear heard, neither hath it entered into the heart of man, what things God hath prepared for them that love him.
A cockroach feeds of garbage .. therefore it will never be in Heaven .. because there will not be garbage there.
Only spiritual beings will be living there.
