Seeing and hearing are an important part of human living and existence. Without seeing we could not see the beauties of the created order around us; neither could we see to navigate as we walk, ride or drive through a countryside.
Without hearing we could not hear the sounds of animals in the creation, neither the cries of our children as young babies crying out for care and nourishment; neither the voices of our spouses and friends, or other family members. We would not be able to hear the warning shouts of someone warning us of an upcoming danger.
These two senses are an important part of human life. They are also an important part of our spiritual existence. In the spiritual realm we can be very easily deceived, unless we have someone in whom we can trust and depend.
In Jesus’s days on earth He taught people, and called people to Himself; teaching them how to live in the Word of God, to do justly, to love mercy, and how to walk humbly with God. Yet, there were many who would not hear; nor would they see who He really is. Jesus says that this too is a fulfillment of prophecy:
“And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive: for this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them. But blessed are your eyes, for they see: and your ears, for they hear.” Matthew 13:14-16 (KJV)
Isaiah is the prophet whom Jesus quotes (Isaiah 6:9-10). The blindness and deafness of the religious leaders was fulfillment of that. It is a truth we cannot neglect to hear. When the truth of Scripture is rejected the truths of God will grow more and more dim; the hearing will fade away into oblivion and there will be no knowledge or understanding of God or His Word.
Those who know God through His Son Jesus Christ love the Word of God, and hide in the heart that we might not sin against God (Psalm 119:11), and make it a light for our path (Psalm 119:105).
The path to understanding God and His Word is through the cross of Jesus Christ who died for our sins, was buried, and bodily arose from the grave. Believe Him, trust His Word. It is the way of life, and life everlasting.
