Every one's posts on this topic are excellent. I find it so interesting that God does not bother to give out a manual when it comes to the gifts, and I think that was smart, as no doubt we would wreck things worse than usual!
People are prone to wanting to control and quantify what God does, and especially in the gifts, that just won't fly.
DTT, some people who have the gift of discernment of spirits see them, (both angels and fallen angels) in our natural realm. Some smell them. I have been told that cancer has a particular smell, and I have no reason to doubt that. Conversely, angels can have a wonderful smell. Some people see nothing, and none of their other senses are involved, but word of knowledge and wisdom operate as to what what is going on and how to pray. Some will see an allegorical picture in their mind and then know how to proceed. It is very different for each person.
Re: discerning the presence of angels, one man who was used in documented miracles as well as in healings during the late '40s used to wait until an angel came and stood beside him. Sometimes the wait was a long one, but he would not begin to pray until he knew that the angel that had been assigned to him was present, and he really took heat for it.
Remember that when God commands us to "earnestly desire the best gifts," that means what is best for you as well as for His people. If you feel that God may want to use you this way, let Him cleanse, prepare and strengthen you to the depths,transform your mind continually, and make the Word of God your standard and passion. That will be your safety, and you won't find yourself "running your lawnmower over a beehive," as Weltan said so perfectly. Good one! :lol:
