I believe that there is everlasting life, because the Bible so teaches.
Matt. 25:46: And these shall go away into everlasting punishment, but the righteous into life eternal.
Joh. 10:28: I give unto them eternal life, and they shall never perish, neither shall any man pluck them out of my hand.
Joh. 3:16: 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.
Heb. 13:14: For here we have no continuing city, but we seek one to come.
