Jesus said to them, ‘I am the bread of life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty. But I said to you that you have seen me and yet do not believe.
Everything that the Father gives me will come to me, and anyone who comes to me I will never drive away; for I have come down from heaven, not to do my own will, but the will of him who sent me.
And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.
This is indeed the will of my Father, that all who see the Son and believe in him may have eternal life; and I will raise them up on the last day.
John 6. 35-40 (NIV)
