In their expert domains of understanding, knowing, loving, compassion, and prophecy, angels clearly have a lot to teach us about spirituality. And their tasks are not trivial. They have serious cosmic duties to perform, relating to the wisdom and the knowledge that they carry. One of these tasks is to praise. Wherever there is praise going on, angels seem to show up.
