While each of the terms in the first three verses is an important symbol with spiritual meaning, we will focus briefly on only one of them, the symbol of "ear" in verse 3. God adds to that term, "come to Me" and "hear, and . . . live." How important is this concept?
Paul writes in Romans 10:17, "So then faith comes by hearing, and hearing by the word of God." "So then" marks this statement as a conclusion. If we desire to be in God's Kingdom, hearing is essential. Such a person must live by faith. Salvation is by grace through faith, and faith comes by hearing. Faith is an absolute necessity, and hearing is equally necessary for having faith that saves.
Interestingly, virtually every modern translation of this verse now reads, "So then faith comes from hearing, and hearing through the word of Christ," or the end may be, "the word concerning Christ." Why make this change? The entire context of the book of Romans presents us with the knowledge of the spiritual foundation for a life in Christ and living by faith. It teaches us how to have a living relationship with the Father and Son, and it focuses on understanding the preaching of Christ. The translation change brings Christ more sharply into focus.
Matthew 17:5 reads: "While he was still speaking, behold, a bright cloud overshadowed them; and suddenly a voice came out of the cloud, saying, 'This is My beloved Son, in whom I am well pleased. Hear Him!'" The One who became Jesus Christ is the same One urging us in Isaiah 55 to seek Him, and a major element in seeking Him is to hear Him. Hearing Him is the path to increasing faith and being enabled to live by faith, thus pleasing God.
The first sentence of the first paragraph of the article, "Ear, Hearing," in The Dictionary of Biblical Imagery reads, "In the Bible the ear is synonymous with the heart and mind as an organ of cognition" (p. 223). The placement of this statement helps emphasize the importance of thoroughly understanding what Christ has said. The Reader's Digest Oxford Complete Wordfinder Dictionary defines cognition as "knowing, perceiving, or conceiving as an act or faculty distinct from emotion and volition." "Understanding," "grasping," and "getting" are synonyms. To come to know Christ obviously requires effort. Biblically, then, the hearing involved in Isaiah 55:1-3 requires concentrated listening, comparing scripture with scripture, and meditated understanding. These lead to living faith and grasping the sovereignty of God over our lives.
