Jesus teaches in the synagogues John 6: 41-56
The verses in this chapter of the book of John show us two essential truths. The first is the truth that believing in Jesus is what sustains life and truly matters. Secondly, not believing in Him has its consequences. When Jesus was teaching in Capernaum, as was many times, the Jewish leaders of the time did not understand Him. The verses here show the confusion in their minds as to what He was saying. Lets look at the first two verses in this section;
The Jews then complained about Him, because He said, “I am the bread which came down from heaven.” And they said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How is it then that He says, ‘I have come down from heaven’?” John 6:41-42
They only knew of Jesus from knowing His father and mother. To them He was just an ordinary man. Further confusion occurred when Jesus answered them and said;
Most assuredly, I say to you, he who believes in Me has everlasting life. I am the bread of life. Your fathers ate the manna in the wilderness, and are dead. This is the bread which comes down from heaven, that one may eat of it and not die. I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.” John 6:47-51
At this point they had no idea what He was talking about. They took everything Jesus said literally. As it will be explained later, this was intentional on Jesus’ part.
The Jews therefore quarreled among themselves, saying, “How can this Man give us His flesh to eat?” Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed, and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him. John 6:52-56
What Jesus was speaking about here is that believing in Him, faith in Jesus is the only way one can have eternal life. Eating His flesh and drinking His blood is the taking in to ones heart and mind of who Jesus truly is, not just a superficial belief. It is symbolic of having true faith. Just as we consume food to live now, the effects of eating food is temporary as this life is. But the taking in of who Jesus is, sustains us forever. The Jewish leaders of the time did not understand this. Mainly because they did not want to believe in Jesus as the promised Messiah.
Often times when we read the scriptures, they can appear to be confusing and not make any sense. I have heard a lot of people say to me this is one of the reasons they do not bother reading the Bible.
Jesus also often spoke in parables. As stated above, this was intentional. In fact at one point, the disciples ask Jesus why He spoke this way;
".....Why do you speak in parables? He answered and said to them, Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever has to him, more will be given and he will have abundance, but who ever does not have, even what he has, will be taken away. Therefore I speak in parables, because seeing they do not see, and hearing they do not hear, nor do they understand." Mathew 13:10-13
What Jesus is saying here is if you truly come to faith, the work of the Holy spirit will help you to understand (for whosoever has to him more will be given). If you do not have faith in our Lord as the Jews did not in the above verses of John, then it is intentionally meant be kept from your understanding (Therefore I speak in parables, because seeing they do not see, and hearing they do not hear, nor do they understand)
So take in the offering of His flesh and blood and choice to live forever. A choice that is beyond our comprehension.
