Isa. 55:1 ¶ Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come ye, buy, and eat; yea, come, buy wine and milk without money and without price. 2 Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness. 3 Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David. To hunger and thirst = desire To drink and eat = satisfying that desire drink and food = sustances for physical life The analogous application here is in verse 3 "incline your ear and come unto me: hear, and your soul shall live" Jn. 6:34 Then said they unto him, Lord, evermore give us this bread. 35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. How does Christ tell them to satisfy their desires for this bread? "he that cometh to meSHALL NEVER HUNGER.and he that believeth on me SHALL NEVER THIRST" Re 22:17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely. How does one satisfy their thirst for eternal life? "come....come...let him that is athirst come...take the water of life freely" To "come" means to believe in Christ and that is what satisfies their thirst (desires) and obtains SPIRITUAL life - the water of life. Jer 15:16 Thy words were found, and I did eat them; and thy word was unto me the joy and rejoicing of mine heart: for I am called by thy name, O LORD God of hosts. Joh 6:68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. 69 And we believe and are sure that thou art that Christ, the Son of the living God. What did Peter identify as "the words of Life"? Answer - "we BELEIVE and are SURE that THOU ART THE CHRIST THE SON OF THE LIVING GOD." Peter partook, eat of the words of life by faith not by injesting literally words Jn. 6:47 Verily, verily, I say unto you, He that believeth on me hath everlasting life. 48 I am that bread of life. How did Jesus instruct them to partake of "OF LIFE" found in Him as bread?Not by injesting his literal flesh but "he that BELEVING ON ME" 1. Hunger, thirst = desire for physical or spiritual things 2. eat, drink = partaking of physical or spiritual things Jesus makes the cross over from the physical to the Spiritual in this analogy TWICE before verses 50-58 and then bluntly tells his disicples that his words were not to be understood in the MATERIAL or PHYSICAL sense but in the SPIRITUAL. Then Peter demonstrates the cross over from physcial showing he understood that he partook of Christ through the "WORDS of life" by faith.
