Jesus said

For the bread of God is he who comes down from heaven and gives life to the world. 
Sir, they said, from now on give us this bread. 
Then Jesus declared, I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty.
John 6:33-35



When Jesus spoke again to the people, he said, I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.
John 8:12


The Shepherd and His Flock
I tell you the truth, the man who does not enter the sheep pen by the gate, but climbs in by some other way, is a thief and a robber. The man who enters by the gate is the shepherd of his sheep. The watchman opens the gate for him, and the sheep listen to his voice. He calls his own sheep by name and leads them out.  When he has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice. But they will never follow a stranger; in fact, they will run away from him because they do not recognise a stranger's voice. Jesus used this figure of speech, but they did not understand what he was telling them. Therefore Jesus said again, I tell you the truth, I am the gate for the sheep.  All who ever came before me were thieves and robbers, but the sheep did not listen to them.  I am the gate; whoever enters through me will be saved. He will come in and go out, and find pasture.  The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.
John 10:1-10



I am the good shepherd. The good shepherd lays down his life for the sheep.
The hired hand is not the shepherd who owns the sheep. So when he sees the wolf coming, he abandons the sheep and runs away.
Then the wolf attacks the flock and scatters it. The man runs away because he is a hired hand and cares nothing for the sheep.
I am the good shepherd; I know my sheep and my sheep know me - just as the Father knows me and I know the Father- and I lay down my life for the sheep.
John 10:11-15



Jesus said to her, I am the resurrection and the life. He who believes in me will live, even though he dies;  and whoever lives and believes in me will never die.
John 11:25-26


Jesus the Way to the Father
Thomas said to him, Lord, we don't know where you are going, so how can we know the way?  Jesus answered, I am the way and the truth and the life. No-one comes to the Father except through me.
John 14:5-6
reflections

The Vine and the Branches
I am the true vine, and my Father is the gardener.  He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes so that it will be even more fruitful. You are already clean because of the word I have spoken to you.  Remain in me, and I will remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. 
I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing.
John 15:1-5
