Hebrews 1:12,
Like a cloak You will fold them up and they will be changed.
But You are the same; and Your years will not fail.

God never changes. He is always the same no matter how the world changes. Sometimes when I feel like Luke will never be healed. God gives me a verse like this just to remind me that He never changes. God still is the same God that did miracles in the Bible and He can heal Luke at anytime. I was so encoraged by this verse and I hope it encorages you too.
