John 6:35 Jesus said to them, “I am the bread of life. Whoever comes to Me shall never hunger, and whoever believes in Me shall never thirst."
In this passage, Jesus is preaching about normal bread that may sustain our bodies for a day, versus the bread of life that gives us new life for eternity.
The previous day He fed the 5000 with a few loaves of bread and some fish. Some of those people followed Jesus hoping He would multiply some food again. Jesus knowing their hearts addresses these people in a message the spans almost the entire chapter. I would encourage anyone interested in this topic to read the whole chapter sometime.
Bread from heaven
The immediate context of verse 35 is as follows, John 6:32-35 Then Jesus said, “Truly, truly I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven. For the bread of God is He who comes down from heaven and gives life to the world.” Then they said to Him, “Lord, give us this bread always.” Jesus said to them, “I am the bread of life. Whoever comes to Me shall never hunger, and whoever believes in Me shall never thirst.
What an amazing way to get the point across. In the desert, God sent mana from heaven to sustain the Israelites. They didn't harvest the wheat, crush the grain and process it into flour, they didn’t make the dough and bake it in an oven. Mana was divinely provided for them and literally fell from the sky. Jesus is saying that just as God provided temporal sustenance, He has also given the Bread of life. Jesus is that bread.
My body which was broken
The comparison is that just as bread provides the energy we need to live, so Jesus provides the means to eternal life. He told his disciples when having supper with them the night before his crucifixion. That the bread they were sharing (as each one broke a piece of the loaf) was like His body which would be broken on the cross.
Where to get your fill
We sometimes only seek God for help with temporal issues. Asking God for a job, for help with debt, or health conditions, or good grades. These are good things that we can ask the Lord’s help with but if we have not repented of our sins and placed faith in Jesus Christ, then we cannot walk in fellowship with Him. He is worthy of honour and glory no matter our situation. Not just when we need something.
