I make known the end from the beginning, from ancient times, what is still to come. I say, "My purpose will stand, and I will do all that I please."
Isaiah 46:10 (NIV)
That God have a purpose and a plan for you and me, God's plan will not fail because He has enough power to ensure His plan is carried out no matter what we may see happening or changing. We change plans when we encounter unexpected events or learn new information. But God doesn't need to change His plans. He knows the end from the beginning and nothing can surprise Him. His purpose will be accomplished because He alone is God, He is with you and for you. God is your refuge and protector.
It's easy to be afraid when things aren't going well or when we face challenges and conflicts in our lives. In the midst of our struggle, however, God is telling you today to wake up and recognize who is on your side. God said "I am the Lord. I am your refuge and your strength. You have nothing to fear or worry about when I am with you. I will fight your battles and deal with your enemies."
So no matter what happens to you today, know that nothing can take God by surprise. God is in control, He has it all figured out, so be still and know that He is God.
