Jesus echoes John 3:16 when he tells the people he is the only one who can supply the bread of life. They can receive that bread only by believing in him, the one sent by God. Those who believe in Jesus will always be satisfied.
John 6:27/29,32-39…43-45 Easy-to-Read Version
27 But earthly food spoils and ruins. So don’t work to get that kind of food. But work to get the food that stays good and gives you eternal life. The Son of Man will give you that food. He is the only one qualified by God the Father to give it to you.”
29 Jesus answered, “The work God wants you to do is this: to believe in the one he sent.”
32 Jesus said, “I can assure you that Moses was not the one who gave your people bread from heaven. But my Father gives you the true bread from heaven. 33 God’s bread is the one who comes down from heaven and gives life to the world.” 35 Then Jesus said, “I am the bread that gives life.

Jesus went on to expand on John 3:16 by explaining, not everyone would believe in him. His believers were given to him by his father and none would be rejected or lost.
36 I told you before that you have seen me, and still you don’t believe. 37 The Father gives me my people. Every one of them will come to me. I will always accept them. 38 I came down from heaven to do what God wants, not what I want. 39 I must not lose anyone God has given me…
Jesus explains only those who are drawn by God can follow him and others cannot.
43 But Jesus said, “Stop complaining to each other. 44 The Father is the one who sent me, and he is the one who brings people to me. I will raise them up on the last day. Anyone the Father does not bring to me cannot come to me. 45 It is written in the prophets: ‘God will teach them all.’ People listen to the Father and learn from him. They are the ones who come to me.
When did you answer your calling by God? What does it look like to be drawn by God? How does God teach the drawn out ones? How do they listen? How should those called, respond? Do they have a choice?
