I believe it is very clear now, why they are called spirits and the lifestyle they live is called spiritual life. Because, just as Aaron and the people, saw Moses and could not come close because of fear; and the disciples (Peter, James and John) marvelled and became amazed when they saw Christ's transfiguration experience; so much that he told them not to tell anyone until after His resurrection. In the same way, I bet you will run faster than a Usain Bolt; when you have any of the heavenly beings coming to live as your next door neighbour, in your neighbourhood. Smiles! Stay blessed.
