"Have you Received His image in your countenance." I think that is what people see. When you've been studying the word and drawing closer to the Lord, He becomes more a part of you and naturally flows out of you. I see it in people's eyes sometimes.

I, too, am very cautious about people who speak as your friend did, but I have learned that for some people it is the love of God flowing out of them, and that for others it is just talk. If you can't tell by their countenance, you can tell by their fruit.
