For God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish but have everlasting life. 

For God sent not his Son into the world to condemn the world, but that the world through him might be saved.

He that believeth on him is not condemned; but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

   John 3:16-18

Let not your heart be troubled: ye believe in God, believe also in me.

In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.

And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.

John 14:1-3
