Jesus had no form of majesty nor beauty to be desired. The centurion looked beyond as he understood the Authority of Jesus- being a man in and under authority himself. " Just say the word" and his servant was instantly healed.
Sometimes that's all we need, for God to speak only one word into our lives and everything changes.Yet even when we don't get immediate answers we are encouraged not to throw away our confidence in God as it will be richly rewarded.
(Mathew 8:5-13, 1John 5:14-15,Hebrews 10:35-38)
