When Jesus directs their work, they will prosper. It "manifested forth His glory". Unbelieving Jews would not see John 2: 23— The element of deity He reveals here is that he transcends time. He has all power in heaven and earth.
There is a reference here to Hos. Once Jesus spoke those words, the man immediately became well. Most notable in John 21, the disciples were regenerated and were now ready to bring others to Christ when they would have been depressed or doubtful before.
One can not help but reflect in the fact that Jesus was present in creation. Of this body.
His life in you in a continuous victory over death which is produced by sin. Do you believe this?
