I, Jesus, came from heaven to the earth to give you my testimony.  I am a king but my kingdom is not of this world.  My kingdom is from another place.  The reason I was born and the reason I came into the world was to testify to the truth.  Everyone on the side of truth listens to me.  John 18:36-37

You are from below.  I am from above.  You are of this world.  I am not of this world.  John 8:23

No one has ever gone into heaven except me - the one who came from heaven.  John 3:13

God so loved the world that he gave his one and only Son.  Whoever believes in me will not perish but have everlasting life.  God did not send me into the world to condemn the world but to save the world through me.  If you believe in me, you are not condemned but if you do not believe, you stand condemned already because you have not believed in the name of God's one and only Son.  John 3:16-18

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

I am the bread of life.  If you come to me, you will never go hungry and if you believe in me, you will never be thirsty.  I will never drive you away.  I have come down from heaven not to do my will but to do the will of him who sent me.  My Father's will is that you look to the Son and believe in me to have eternal life and I will raise you up at the last day.  John 6:35,37-38,40

No one has seen the Father except the one who is from God.  Only I have seen the Father.  I tell you the truth, if you believe in me, you have everlasting life.  John 6:46-47

If you are thirsty, come to me and drink.  If you believe in me, rivers of living water will flow from within you.  John 7:37-38

If you drink the water I give you, you will never thirst.  The water I give you will become a well of water in you springing up to everlasting life.  John 4:14
