Have you ever wondered what the purpose could be for mosquitoes?  I know he created them. If what is on earth is in Heaven because Yeshua said we are to pray that His will is done on earth as it is in Heaven?  I don't believe there is darkness in Heaven - even if there was a cave there would be no darkness because God is light and in Him there is no darkness.

Paul said, "It is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him" (1 Cor. 2:9).
