John 6:60-63 NIV

[60] On hearing it, many of his disciples said, “This is a hard teaching. Who can accept it?” [61] Aware that his disciples were grumbling about this, Jesus said to them, “Does this offend you? [62] Then what if you see the Son of Man ascend to where he was before! [63] The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit and life.
