Right after God told Moses what He would do, He said to him, "You must believe it. I command you to do this thing." "Now the LORD spoke to Moses and Aaron about the Israelites and Pharaoh king of Egypt, and he commanded them to bring the Israelites out of Egypt" (v. 13 NIV).
God was saying, "This is going to happen. The Israelites will come out of Egypt. This isn't wishful thinking or a nice sentiment. I intend to bring it to pass. Get ready to execute the plan."
So often the arrow that penetrates our soul at the weakest point is our unbelief. We know in our heads what God has said, but it takes faith to put it into gear, to get out there and start practicing what He has told us to do. Then and there, at that split-second of hesitation, the battle is won or lost.
This is how we need to pray, even when we feel as if we never want to pray again: "Lord, I don't feel like praying right now, but hear my prayer anyway. Lord, I will believe You, even though the tide is rising, and I'm already on tip-toe. I will believe You, even though it seems like it's taking You forever to keep Your promise. I will believe You, even though I've come to the ragged end of my strength, the dregs of my hope, the broken shards of my plans. I will not look for a shortcut. I will not rely on a carnal option. I will not retreat from the battle. I will believe You!"
God's promise to Moses is the same to us: "Because I am who I am, I will do what is best for you." There isn't a day on this side of eternity, no matter how grim, that can't be improved by clinging to that reassuring thought.
A bad day will improve if you cling to God’s promise to do what is best for you.
