46 As he traveled through Galilee, he came to Cana, where he had turned the water into wine. There was a government official in nearby Capernaum whose son was very sick. 47 When he heard that Jesus had come from Judea to Galilee, he went and begged Jesus to come to Capernaum to heal his son, who was about to die. 48 Jesus asked, "Will you never believe in me unless you see miraculous signs and wonders?" 49 The official pleaded, "Lord, please come now before my little boy dies." 50 Then Jesus told him, "Go back home. Your son will live!" And the man believed what Jesus said and started home. 51 While the man was on his way, some of his servants met him with the news that his son was alive and well. 52 He asked them when the boy had begun to get better, and they replied, "Yesterday afternoon at one o'clock his fever suddenly disappeared!" 53 Then the father realized that that was the very time Jesus had told him, "Your son will live." And he and his entire household believed in Jesus. 54 This was the second miraculous sign Jesus did in Galilee after coming from Judea.

Commentary on John 4:43-54
(Read John 4:43-54)
The father was a nobleman, yet the son was sick. Honours and titles are no security from sickness and death. The greatest men must go themselves to God, must become beggars. The nobleman did not stop from his request till he prevailed. But at first he discovered the weakness of his faith in the power of Christ. It is hard to persuade ourselves that distance of time and place, are no hinderance to the knowledge, mercy, and power of our Lord Jesus. Christ gave an answer of peace. Christ's saying that the soul lives, makes it alive. The father went his way, which showed the sincerity of his faith. Being satisfied, he did not hurry home that night, but returned as one easy in his own mind. His servants met him with the news of the child's recovery. Good news will meet those that hope in God's word. Diligent comparing the works of Jesus with his word, will confirm our faith. And the bringing the cure to the family brought salvation to it. Thus an experience of the power of one word of Christ, may settle the authority of Christ in the soul. The whole family believed likewise. The miracle made Jesus dear to them. The knowledge of Christ still spreads through families, and men find health and salvation to their souls.
