I have spoken to you of earthly things and you do not believe.  How then will you believe if I speak of heavenly things?  No one has ever gone into heaven except the one who came from heaven, the Son of Man.  Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up, that everyone who believes in him may have eternal life.  John 3:12-15

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.  God did not send his Son into the world to condemn the world, but to save the world through him.  Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.  John 3:16-18

Everyone who drinks this water will be thirsty again, but whoever drinks the water I give him will never thirst. Indeed, the water I give will become in him a spring of water welling up to eternal life.  John 4:13-14

You diligently study the Scriptures because you think that by them you possess eternal life.  These are the Scriptures that testify about me, yet you refuse to come to me to have life.  John 5:39-40

Do not work for food that spoils but for food that endures to eternal life which the Son of Man will give you.  On him, God the Father has placed his seal of approval.  John 6:27

I tell you the truth, it is not Moses who has given you the bread from heaven, but it is my Father who gives you the true bread from heaven.  For the bread of God is he who comes down from heaven and gives life to the world.  John 6:32-33

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 6:35 

I have come down from heaven not to do my will but to do the will of him who sent me.  And this is the will of him who sent me, that I shall lose none of all that he has given me but raise them up at the last day.  For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise them up at the last day.  John 6:38-40

No one has seen the Father except the one who is from God.  Only he has seen the Father.  I tell you the truth, he who believes has everlasting life.  I am the bread of life.  John 6:46-48 

I am the living bread that came down from heaven.  If anyone eats of this bread, he will live forever.  This bread is my flesh which I will give for the life of the world.  John 6:51

If anyone is thirsty, let him come to me and drink.  Whoever believes in me, as the Scripture has said, will have streams of living water flow from within him.  John 7:37-38

You are from below, I am from above.  You are of this world, I am not of this world.  I told you that you would die in your sins.  If you do not believe that I am the one I claim to be, you will indeed die in your sins.  

John 8:23-24

When you have lifted up the Son of Man, then you will know that I am the one I claim to be and that I do nothing on my own but speak just what the Father has taught me.  John 8:28

If you hold to my teaching, you are really my disciples.  Then you will know the truth and the truth will set you free.  John 8:31-32

I tell you the truth, if anyone keeps my word, he will never see death.  John 8:51

While I am in the world, I am the light of the world.  John 9:5

I am the gate.  Whoever enters through me will be saved.  John 10:9

The reason my Father loves me is that I lay down my life only to take it up again.  No one takes it from me, but I lay it down of my own accord.  I have authority to lay it down and authority to take it up again.  This command I received from my Father.  John 10:17-18

My sheep listen to my voice.  I know them and they follow me.  I give them eternal life and they shall never perish.  No one can snatch them out of my hand.  John 10:27-28

I and the Father are one.  John 10:30

I tell you the truth, unless a kernel of wheat falls to the ground and dies, it remains only a single seed.  But if it dies, it produces many seeds.  John 12:24

Now is the time for judgment on this world.  Now the prince of this world will be driven out.  But I, when I am lifted up from the earth, will draw all men to myself.  John 12:31-32

I have come into the world as a light so that no one who believes in me should stay in darkness.  As for the person who hears my words but does not keep them, I do not judge him.  For I did not come to judge the world but to save it.  There is a judge for the one who rejects me and does not accept my words.  That very word which I spoke will condemn him at the last day.  John 12:46-48

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.  John 15:1-2

Father, I want those you have given me to be with me where I am and to see my glory, the glory you have given me because you loved me before the creation of the world.  John 17:24

My kingdom is not of this world.  If it were, my servants would fight to prevent my arrest by the Jews.  My kingdom is from another place.  John 18:36

You are right in saying I am a king.  In fact, for this reason I was born and for this I came into the world, to testify to the truth.  Everyone on the side of truth listens to me.  John 18:37

Put your finger here and see my hands.  Reach out your hand and put it into my side.  Stop doubting and believe!  Because you have seen me, you have believed.  Blessed are those who have not seen and yet have believed.  John 20:27-29

How do you get to heaven?
