There is no reason to be afraid when you realize what God has done for you. He formed you (v. 1) and made you for Himself (v. 21) and for His glory (v. 7). When you trusted Jesus Christ, God redeemed you (v. 1) and blotted out all your sins (v. 25). He is “the Lord, your Holy One, the Creator of Israel, your King” (v. 15). He loves you (v. 4) and knows your name (v. 1). What a privilege to belong to such a great and gracious God!
Even more, God promises to be with you (v. 5) and take you through the water and the fire (v. 2). At the Exodus, He took Israel through the Red Sea and defeated the Egyptian army (vv. 16–17). Perhaps the three Hebrew heroes claimed this promise when they faced the fiery furnace (Dan. 3).
In spite of all the ministry He shares with us, God does not get weary as we do (40:28); but we can weary Him with our empty religious ritual and our sins (vv. 22–24). You are precious in His sight (v. 4), so do not cheapen yourself by disobeying Him.
