Selwyn continues to look at his first, ’hard’ saying of Jesus: “Unless you can eat the flesh of the Son of Man and drink His blood, you have no life in you.” (John 6:53)
As Selwyn says, the people following Jesus where doing so because of the benefits that flowed to them; those who were sick were healed, at lunch-time the crowd was feed with fish and bread. They did not have to do much as individuals, but as part of a crowd they could freely follow Jesus around Galilee and receive free gifts.
Then Jesus points out that that those who ate the ‘manna’, the food provided by God in the desert (in the time of Moses) still died.  Jesus then tells them that He can provide food that when eaten will result in eternal life – this food is Him, eat what He is offering, and live forever.Â
I like the words of Jesus recorded in John 4:10-13; “Jesus answered her, ‘If you knew the gift of God and who it is that asks you for a drink, you would have asked him and he would have given you living water.’ ‘Sir,’ the woman said, ‘you have nothing to draw with and the well is deep. Where can you get this living water? Are you greater than our father Jacob, who gave us this well and drank from it himself, as did also his sons and his flocks and herds?’
Jesus answered. ‘Everyone who drinks this water will be thirsty again, but whoever drinks the water I give them will never thirst. Indeed the water I give them will become in them springs of water welling up to eternal life.’”
Jesus provides us with spiritual food that sustains our spiritual life. What are your views?
