In Christian theology, the concept of eternal life is often linked to knowing God and Jesus Christ. This interpretation stems from John 17:3 in the New Testament, which states, "Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent." In this context, "knowing" goes beyond mere intellectual understanding; it implies a deep, personal relationship with God through Jesus Christ. This relationship is believed to begin in the present life and continue into eternity. The idea is that through faith in and following of Jesus, one enters into a state of being reconciled with God, which is considered the essence of eternal life. This concept of eternal life is not just about duration (living forever) but also about quality of life - a life in communion with God. It's seen as a gift from God, received through faith, rather than something earned through good deeds.
