In Luke 18 and 19, Jesus singles out two men as He passes through Jericho: one guy is physically blind but able to see spiritually, and the other guy is spiritually blind but able to see physically. They each need a personal encounter with Jesus in order to "see". And when that happens, they both are able to see physically and spiritually. There are plenty of people in this world who have physical sight, but are blind to spiritual things. Only a personal encounter with Jesus will open the eyes of their heart.
