Boyd K. Packer: It’s a very fine line to determine whether the impression or prompting is revelation or just a personal thought. One of the tests is to ask yourself, is it good? Does it make you happy? Or is it destructive? You can test. I’ve known many people who have had promptings and found later that they were not right. When they are not right, you can see that they are not right. There’s a power called discernment. To discern is to see. And the power of discernment is one of the gifts that attends the priesthood. If all we knew is what we see and what we hear and what we read, we don’t know much comparatively. The power to discern and to see and to understand is one of the motivating influences of the gospel. And that’s how you know.
