The man believed the word that Jesus spoke and went on his way. John 4:50 ESV1
Read John 4:45-54
“Faith is the assurance of things hoped for, the conviction of things not seen” (Hebrews 11:1) Today, we meet a father who believed in the possibility of something he had never before seen. He took a chance and asked of Jesus that which was contrary to reason. His faith was rewarded. On the contrary, to those who wanted proof before they would believe, Jesus gave chastisement.
