ANSWER: Eternal life is included in the gift of the Son of God. See 1 John 5:11, 12, "And the witness is this, that God gave unto us eternal life, and this life is in his Son. He that hath the Son hath the life; he that hath not the Son of God hath not the life." The life is more than existence; it is well-being; and to all persevering believers it is eternal well-being. Says Alford, "believing and having eternal life are commensurate; where faith is, the possession of eternal life is; and when the one remits, the other is forfeited." Everlasting life is through Christ the Redeemer; everlasting existence is through God the Creator.
