It is not always possible to recognize God's blessing if there is a preconceived concept.
He says that He will withhold no good thing. Can He be trusted? When there has been heartache and loss, can He be trusted? When the schedule breaks down can He be trusted?
The sense of comfort must be in relying on Him - not in evaluating circumstances.
Soldier of The Cross, you have the Power to trust. Step out, even when you can not see the ground. You have been saved by The Rock of Ages. He knows what He is doing, even if you do not.
Tell Him you will trust Him. If you are having difficulty letting go of the matter, write it on a little piece pf paper and hold it up to Him, telling Him you are yielding to Him.
Tell Him aloud.
