Like someone opened up my head and dropped something inside of it. Like a light being turned on in a dark room that you didn’t realize was wired for electricity. Like the feeling of seeing a jigsaw puzzle piece that fits.
I also get ideas, lots of ideas, more ideas of my own than inspiration from outside of myself. And again, discerning one from the other is not always easy, but it’s also not always necessary. There’s a distinction between good discernment and good judgment, but if you have the latter you won’t always need the former, because the stupid ideas will be tossed out without knowing that they weren’t inspired.
