It is too easy to think, In the Lord's true Church, our standard of performance should be higher than that. There is more than one way to help the Lord lift them to that standard. One is to express or show our displeasure. I've been the beneficiary of another way, the better way. I've sensed when I was not doing very well when I was speaking or teaching or leading in a meeting.
Most people can tell when they are failing.
I have been able to tell when I have been not doing well, and I've looked out and seen someone in the audience apparently not paying attention to me, with eyes closed. I've learned not to be irritated. And then they've opened their eyes and smiled at me, with a look of encouragement that was unmistakable. I know the Lord will help you and lift you up. I'm praying for you.
