Really want to know about eternal life? The Bible inextricably links eternal life with the Person of Jesus Christ. John 17:3 is an important passage in this regard, as Jesus prays, “Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.” http://www.gotquestions.org/what-is-eternal-life.html

Notice the words of Jesus as he prayed in John 17:3, "And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent." There is no eternal life without knowing Jesus Christ. We'll explain later exactly what "knowing Jesus" means. Jesus said in John 14:6, "I am the way, the truth, and the life: no man cometh unto the Father, but by me." Can a person come to God without Jesus? Well...Jesus himself says emphatically "NO" in that verse. There is no alternative means by which one may reach Heaven. That brings us to another disputed point among the cults - the concept of those in Christ going to Heaven. There are those who teach that eternal life does not mean that we spend it in Heaven. Two passages of scripture dispute that fallacy. I Peter 1:3-4 says, "Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead, To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you," Also notice II Corinthians 5:1, "For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens." That's pretty indisputable I'd say; eternal life means going to Heaven. http://www.bibletrack.org/notes/resource/misc/Eternal_life.html
