I've been in situations before when I would think something and know that whatever it was would be pleasing and God honoring on the surface, but felt a strong sense from God to not go through with it. These situations would turn out to glorify God and be for my good later on, but I would have never known that at the initial time it came into my head to do whatever it was. My advice is this: When something pops in your head..weigh it out with the word of God and pray on it. Pray on it more. Then pray on it more. I cannot stress the importance of prayer here. Bottom line..Trust & Obey.
