The God who created everything is the only One who can judge what is beautiful. Only He has the right to call anything good or bad, because He alone keeps everything in order. He alone knows everything and the reason behind it.
Now, beloved, He is calling you beautiful. Won’t you believe Him? He is worthier of your trust, than the people who never knew your story or your emotions which always vary. God calls you beautiful. That’s who you are in His eyes for all eternity. Believe Him.
