I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit.  Flesh gives birth to flesh, but the Spirit gives birth to spirit.  You should not be surprised at my saying, "You must be born again."  John 3:5-7

The Spirit gives life.  The flesh counts for nothing.  The words I speak to you are spirit and they are life.  

John 6:63

Whoever hears my Word and believes in the one who sent me has eternal life and will not be condemned.  They have crossed over from death to life.  John 5:24

I have come that you might have life and have it more abundantly.  I am the good shepherd.  The good shepherd lays down his life for the sheep.  John 10:10-11

John 8:12

Enter through the narrow gate.  Wide is the gate and broad is the road that leads to destruction and many enter through it.  But small is the gate and narrow is the road that leads to eternal life and only a few will ever find it.  Matthew 7:13-14

What good is it for you to gain the whole world and lose your very own soul?  Matthew 16:26

Matthew 10:32-33

Here I am!  I stand at the door and knock.  If you hear my voice and open the door, I will come in and eat with you and you with me.  Revelation 3:20
