If you're living a yielded life, and if you have the preaching and teaching gift, and you're yielding that to God on a continual basis, that's one of the signs that you're in the right place doing the right thing for the right reasons. If you're doing something in the kingdom, and you rarely feel that, that's a red flag. Something needs to be looked at. Are you using the right gift? Are you using it in the right way? For the right reasons? At the right time? In the right context? If I didn't feel it consistently, that would be quite troubling to me.
