I do not approve of this phrase: "Rest In Peace Michael" and i never has said it for Him.
Is it really resting? only His body which he had left here for us is laid to rest but we believe that His soul is in heaven, dancing and Moonwalking with angels... so it is not like resting...
Michael IS... He is somewhere up in heavens... He exists .... so We may pray:
"Be in Peace Michael"
What you think?
