What does it mean to have eternal life according to the gospel?

Eternal life is not merely an endless existence but is defined in John 17:3 as knowing the only true God and Jesus Christ. This relationship is characterized by intimacy and trust, leading to a life that reflects God's grace and purpose. It is a life that can never be lost, rooted in the assurance that Christ, as the Good Shepherd, will never lose any of His sheep. The gospel promises that believers will not only live eternally but will experience abundant life, filled with meaning, purpose, and the indwelling presence of the Holy Spirit.
