Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? He answered and said, Who is he, Lord, that I might believe on him? And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. And he said, Lord, I believe. And he worshipped him. (John 9:35-38)
In John 9, Jesus heals a man who had been blind from birth (John 9:1). He fixes his physical condition of blindness and that was a definite reason for rejoicing! However, that wasn’t the man’s biggest problem. As we see in the verses above, Jesus deals with that later in the chapter. Although the man had his blindness taken away, he still needs spiritual help.
We all have physical problems that are frustrating, weakening, or even debilitating. But that is a temporary situation. Our spiritual condition lasts for eternity and that makes it more important that our physical maladies.
The man had been saved from blindness, but still needed to place his faith in Jesus for his ultimate salvation from his sin. Jesus presents Himself as the Son of God, that is, God in the flesh (John 1:14; 5:18). The blind man receives Him and his spiritual problem is solved (John 1:12). The same is true for people today who are spiritually blinded. Jesus died on the cross for all of our sins, was buried, and rose again (1 Cor. 15:3-4). He did that to pay the price for our sins (Romans 6:23) and provide a way of salvation for all who believe in Him.
