We can find tremendous comfort in this passage. God is eternal. He has always been there and will always be there. He never gets tired, as we do. In fact, He gives us strength when we are weary. He understands things we cannot begin to understand and He helps us when we are weak. He is our strength and refuge. We can count on Him.
And we pray:
Father, I thank You for giving me strength when I grow weary. I praise You for Your wisdom and understanding. You are faithful to me in all Your dealings. Your Love and Your strength endure forever. Amen.
