If the Lord came to you, assuring you He would be in control of every detail regardless of how it seemed, and asked you to take on the thing you are going through now, you would have gladly said yes.
Now you are struggling with loneliness, frustration, impatience and a helpless, drowning feeling because it seems things will never be resolved as you think they should be.
Yet, He has come to you and has given you His Word that you can hold in your hand, His Word with which you can feed your mind and His Word which calms the emotions.
He has assured you over and over that not only is He in control, but that He does not make mistakes.
It has to do with faith and putting your weight on His Promises and the whole of His Word.
You are a Soldier of The Cross. You have already decided to walk by faith and to let Him call all the shots, even when you are sure things are the reverse of how they should be. He does care about our lives and wants us to trust Him and glorify Him before the unseen hosts. Remember the beginning of the Book of Job? The Lord said to satan, "Have you seen my servant Job?"
Put your name in the question in place of Job's.
You told Him you would follow Him. There is no learning of Him without walking by faith and there is no faith without the need to exercise it.
Faith is exercised only when God is not limited by our running ahead of Him or our refusing to be humble in prayer about the matter.
Often the Lord speaks to us through the very things we say to Him in prayer. Come to Him today and as you are standing before Him, declare again that you are a Blood-bought Soldier. List to Him the reasons you know He is in control. Tell Him you intend to let Him have full play and you will follow Him moment by moment.
Do this alone and aloud.
