God's self-revelation is a higher authority than our feelings.

Scripture assumes that we will be afraid and anxious sometimes. What is important is where we turn, or to whom we turn when we are afraid. The God who calls you to trust in Him when you are afraid will spend a great deal of time showing you that you can trust Him.

Worry’s magnetic attraction can only be broken by a stronger attraction, and David is saying [in Psalm 27] we can only find that attraction in God Himself.

Are you worried? Jesus says there is nothing to worry about. It isn’t our kingdom, it’s God’s. We take our cue from the King, and the King is not fretting over anything. He is in complete control.
