Jesus performed many miracles, using them to show His grace and power and help many who were blind to his purpose and meaning to finally see the Way. No better examples are found than the story in the Gospel of John, Chapter Nine, where he heals the man who was born blind.
One day as Jesus walked by a blind man seated in a place where he might get a few coins from sympathetic passers by, his disciples asked Him, "Who was responsible for the sin that caused the man to be punished in such a way, Master, his parents or himself?" Jesus answered without hesitation by telling them that no one was punishing him, but his affliction was being used by God as a means of showing him the Way.
He knelt down beside the man and spat ono the ground, then formed with His hands two eye covers out of the resulting clay which he placed on the man's eyes. He told him to go to the Pool of Siloam (meaning sent) and wash his face. Siloam was a man made pool created at the end of a water canal which was built to bring water into the City from a river outside the walls. It was to provide water in a time of siege, not uncommon from foreign invaders at the time.
Upon washing, the man who had never experienced sight could now see clearly. His friends and neighbors were skeptical and the Pharisees at the Temple didn't believe. They even called this adult man's parents to validate, but all they would say was that the man could see but they didn't know how it came about. You see, all except the man didn't believe. The parents clearly knew but were afraid to proclaim Jesus for all were warned that anyone believing the Christ would be excommunicated from the Temple. But the man who could now see, despite the threat, stood his ground about the story, listened to the words of Jesus and followed Him, and accepted banishment from the Synagogue rather than denying Him.
The story is a a good biblical example of the words cited in the hymn quotation. And, of course, the message applies directly to spiritual sight, because while many of us can physically see, we are often at the same time spiritually blind. If you want to inherit the Glory of God's Kingdom when this life is done, open your spiritual eyes by opening your heart to Jesus. Then you will truly no longer be blind and your sight will be brighter and more beautiful than you could ever imagine.
Praise God for all things and thank Him for the wondrous gift afforded us through the death of His Son, our Lord and Savior Jesus Christ. Accept His gift of spiritual sight and live forever. Hallelujah! .
