Spiritual blindness
John 9: 35-41
35 Jesus learned that the man had been expelled, and when he found him he asked:
"Do you believe in the Son of man?"
36 "Who is it, Lord?" Tell me, to believe in him.
37 "Well, you've seen it," Jesus replied; He is the one who is talking to you.
38 "I believe, Lord," the man declared.
And, prostrating, he worshiped it.
39 Then Jesus said:
"I have come to this world to judge it, so that the blind will see, and those who see will go blind."
40 Some Pharisees who were with him, hearing him speak like this, asked him:
-That? Are we blind too?
41 Jesus answered them:
—If they were blind, they would not be guilty of sin, but, as they say they see, their sin remains.)

This is the way the world goes spiritually, even though they walk and move from one place to another, they stumble because they cannot look spiritually so that their foot does not slip along the wrong paths.
In that sense the world has always misrepresented the things of the spirit, that is, the words that Jesus came to say to mankind so that they could change their lives and no longer walk in darkness. It is for this reason that today many people can clearly look at everything around them but that does not mean that they are not spiritual blind because although you can look at everything if you do not have the ability to believe in Jesus to look at spiritual things you are blind .
In this story we find a meeting of a man with Jesus who had this impediment, so Jesus comes over and asks him, do you believe in the son of man? and he quickly tells her who is it, Lord? This man had Jesus with him but could not recognize him because he was spiritually blind like many people today who cannot recognize Jesus as the savior of his life.
However, when Jesus shows himself to him, this man immediately recognized and could see him as he really was as his lord and savior and immediately fell down before him and worshiped him.
Because Jesus really came to this world to give sight to the blind so that everyone who had his heart to seek him would find life and light would shine forever in his life and would no longer walk in darkness.
