"Like sheep, we can tend to be too clued in to our immediate surroundings, especially when those surroundings produce anxiety, worry, or fear. We may not "see" or remember well what our Shepherd has already done for us, nor be able to "see" very well what He has for us straight ahead. Sometimes when He wants us to move forward, all we can see are the obstacles to what we know He is calling us to do."
