What do the scriptures teach about eternal life?

Scripture teaches that eternal life is granted through faith in Jesus Christ, affirmed by Himself, stating, 'This is life eternal, that they might know thee' (John 17:3). This intimate knowledge of God through Christ forms the essence of eternal life. Moreover, it is revealed that this eternal life is not merely a future hope but a present reality for believers, as echoed in 1 John 5:12, which states that having the Son means possessing this life now. It's a life that is perpetually sustained by Christ, transcending physical death and guaranteeing an everlasting future with Him in glory.
