It's a feeling that I get from time to time about certain issues. I have the feeling God's spoken, but people or situations come up and tell me that what I've heard isn't true or God can't bring the situation round to what is right.
I was reading in II Chronicles this morning about a Jewish King, Hezekiah, being faced with an army that had invaded his land and were threatening to besiege and capture Jerusalem. Messengers were sent to tell both him and the people in Jerusalem that none of the other gods of the nations the invaders had already beaten were able to save their peoples, and that hezekiah's god would be the same. The outcome is, of course, that God deals with the invaders in His own way, and the city is saved without Hezekiah having to deal with the invaders.
There's a subtle touch too. Hezekiah diverted water from a certain spring and built a long tunnel (>1000 feet through solid rock - V hard work) in order to ensure there was a supply of water in the city, so that whatever went on outside the walls, they would never run out of fresh water.
I felt like God spoke to me out of this. That whatever people seem to be doing around me, He'll deal with it His way and I should look to Him for saving/vindication and not try to engineer it myself. There was also a need to go deep, to dig down and have long roots to find fresh water through difficult places. I just wish I didn't struggle with wanting to see it happen and be in some semblance of control - it's so difficult to trust God when He seems to have given everyone free will and they appear to be enthusiastic to exercise it!
