"When any child of God decides to step out in absolute obedience to the will of God, there will be a frantic effort by the powers of darkness to block him. Obstacles will spring up to hinder that one. The possibility of obedience will seem more and more hopeless. When things are the blackest and most discouraging is the very time not to give up. That kind of namby-pamby surrender will be quickly swamped. To keep looking at our difficulties will also swamp us. We need to look resolutely away from the impossibilities and to the Lord. His help will come, through often it cannot break through to us until the last moment. It is very important that we be ready and prepared for action up to the last split second. God does not even mess that split second. He may seem to be delayed, but he will not be too late for the expectant soul waiting in active faith." In the Arena by Isobel Kuhn Does this quote encourage you or dishearten you? How can you apply this quote to all the busyness that is going on right now? What Scripture passage will help you through this busy time? How is God helping you through this time?
