Look at Luke 18:35 – 43…
35 As he drew near to Jericho, a blind man was sitting by the roadside begging. 36 And hearing a crowd going by, he inquired what this meant. 37 They told him, “Jesus of Nazareth is passing by.” 38 And he cried out, “Jesus, Son of David, have mercy on me!” 39 And those who were in front rebuked him, telling him to be silent. But he cried out all the more, “Son of David, have mercy on me!” 40 And Jesus stopped and commanded him to be brought to him. And when he came near, he asked him, 41 “What do you want me to do for you?” He said, “Lord, let me recover my sight.” 42 And Jesus said to him, “Recover your sight; your faith has made you well.” 43 And immediately he recovered his sight and followed him, glorifying God. And all the people, when they saw it, gave praise to God.
Kent Hughes in his commentary on Luke 18:35 – 43 says, “There is only one thing worse than blindness, and that is not knowing that you are blind. Multitudes are blind to their darkness, blind to their sin, blind to their destiny, blind to their hopelessness, spiritually out of touch.”
