When Jesus said we must eat His flesh and drink His blood (John 6:53–56), He was not speaking of chewing His actual body or drinking His physical blood. He was using strong, living words to make people see that just as food and drink enter our bodies to give life and strength, He Himself must enter into us to give us eternal life. Physical bread keeps the body alive for a short time, but Jesus said, “I am the bread of life. He who comes to Me shall never hunger, and he who believes in Me shall never thirst” (John 6:35). This means He alone can satisfy the hunger of our soul and give life that never ends.
To “eat” His flesh and “drink” His blood is to accept Him completely — to trust in His sacrifice on the cross, where His body was given and His blood was poured out for the forgiveness of sins. We take Him into ourselves by faith, by listening to His words, by obeying Him, and by letting His Spirit change us from within. Just as food becomes part of our bodies, Jesus becomes part of our very life.
This teaching was pictured at the Last Supper when Jesus took bread, gave thanks, broke it, and said, “Take, eat; this is My body.” Then He took the cup and said, “This is My blood of the new covenant, which is shed for many for the remission of sins” (Matthew 26:26–28). He gave His disciples bread and wine as symbols, pointing to the truth He taught in John 6 — that His life given for us must be received personally and fully.
So, when we believe in Him, follow Him, and remember His sacrifice, we are truly “eating” the bread of life and “drinking” the cup of salvation, and He becomes our life now and forever.
