In a small town in Indonesia, there was a man who lived alone and could not see. He was blind and yet, he carried a lighted lamp with him whenever he went out at night.
One night, while coming home from a dinner with friends, he came across a group of young travelers. They saw that he was blind, yet carrying a lighted lamp. They started making fun of him. One of them chided, “Hey man! You are blind and can’t see anything! Why then, do you carry a lamp?!”
The blind man replied, “Yes, unfortunately, I am blind and I can’t see anything. The lamp which I am carrying is for the people like you who can see. I fear you may not see the blind man coming and could end up hitting me and hurting me. This is why I carry a lighted lamp”.
Jesus put it this way, You will be ever hearing but never understanding; you will be ever seeing but never perceiving. For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.’ But blessed are your eyes because they see, and your ears because they hear. For truly I tell you, many prophets and righteous people longed to see what you see but did not see it, and to hear what you hear but did not hear it.
Jesus equates calloused hearts with blind eyes. When is the last time you had your eyes checked?
