Hear Jesus words and believe in your heart, trust Jesus words beyond all your reasoning and understanding because He said it. This is believing in Jesus, this is Faith.
“Let us then in everything believe God, and gainsay/deny Him in nothing, though what is said seem to be contrary to our thoughts and senses, but let His word be of higher authority than both reasonings and sight. Thus let us do in the mysteries also, not looking at the things set before us, but keeping in mind His sayings. For His word cannot deceive, but our senses are easily beguiled. That hath never failed, but this in most things goeth wrong. Since then the word saith, ‘This is my body,’ let us both be persuaded and believe, and look at it with the eyes of the soul. For Christ hath given nothing sensible, but though in things sensible yet all to be perceived by the soul. So also in baptism, the gift is bestowed by a sensible thing, that is, by water; but that which is done is perceived by the soul, the birth, I mean, and the renewal. For if thou hadst been incorporeal, He would have delivered thee the incorporeal gifts bare; but because the soul hath been locked up in a body, He delivers thee the things that the mind perceives, in things sensible. How many now say, I would wish to see His form, the mark, His clothes, His shoes. Lo! Thou seest Him, Thou touchest Him, thou eatest Him. And thou indeed desirest to see His clothes, but He giveth Himself to thee not to see only, but also to touch and eat and receive within thee.” John Chrysostom, Gospel of Matthew, Homily 82 (A.D. 370).
Jesus tells you that His flesh is real food and blood real drink. Jesus tells you that you must eat His flesh and drink His blood. Believe it, stand on His Word and believe and obey.
Jesus, whose words stand Eternally, though heaven and earth pass away. Believe them because they are far higher than all man’s reasonings and sight.
Jesus words can never deceive.
