Charles Spurgeon Commentary John 6:35-36

"Jesus said unto them. I am the bread of life: he that cometh to me shall not hunger, and he that believeth on me shall never thirst. But I said unto you, that ye have seen me, and yet believe not." — John 6:35-36 (ASV)

And Jesus said to them, I am the bread of life: he that comes to me shall never hunger; and he that believes on me shall never thirst. But I said to you, That you also have seen me, and believe not.

These were the very people whom he had fed on the other side of the sea; yet they were craving for more. That kind of bread cannot stay their hunger for long. They had not received him as their Savior, else they would have been well content with him, and would have asked for nothing more.
