3:15That whosoever believeth in him should not perish, but have eternal life.

3:16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

6:40And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.

6:47Verily, verily, I say unto you, He that believeth on me hath everlasting life.
