John 4:50

‘Jesus says to him, “Go on your way, your son lives.” The man believed the words that Jesus spoke to him and he went his way.'

So Jesus put his faith to the test. ‘Go your way, your son will live', He said. Compare, ‘Draw out now and bear to the ruler of the feast' (John 2:8). There too the drawers had had to exercise faith simply because Jesus had commanded it. Many would have hesitated and wanted more assurance, or pressed Jesus to come in person, but crucially the man believed the word that Jesus spoke to him. Here at least was one man who had confidence in Jesus and His word. He had no doubts. He went confidently on his way. Jesus had thus achieved a number of things. He had not openly done a wonder and thus brought about a desire in people for more wonders. He had made the man think deeply about what and why he was seeking. And He had revealed that compassion that never failed those in need.
