This is the third of John's miracles. The people believed that the first one into the water after the stirring of the waters would be healed. There is some question about this, for in the earliest copies of John's gospel, the fourth verse is missing. The changing of the water to wine and the healing of the nobleman's son. To prove to readers that Jesus was the Messiah, the Son of God.
All hope is gone.
There is no hope apart from Christ. In grace, the Lord came to the man. In the same way, the Lord Jesus comes to us, and by His sovereign grace, we are healed. The healing was immediate and complete, and so is salvation. Remember that you have the enabling power of the Holy Spirit to deal with your problems.
