本文探讨约翰福音中“永生”(ζωή αἰώνιος)的概念及其神学意涵。透过回顾学界对“永生”内涵的四种主要看法:(一)恒常的生命、(二)真实、崭新、属灵的生命、(三)将来时代的生命、(四)复活的生命,本文指出其中以“复活生命说”最为明确清晰。进一步探讨永生是今世抑或未来之事,作者归纳绝大多数学者支持“今世论”,认为永生是信徒在今生即可获得,同时也具有未来面向,呈现“永生的二阶段论”。最后,本文分析如何获得永生的问题,指出在约翰福音中,“信”是唯一、必要也足够的条件。然而这个“信”并非一般、表面的相信,乃是委身于基督,与基督合而为一的信。总之,本文透过对永生的多维度分析,阐明了约翰福音的核心信息:“信耶稣得永生”的丰富内涵及重要神学意义。
This paper explores the concept of "eternal life" (ζωή αἰώνιος) in the Gospel of John and its theological implications. By reviewing four main interpretations of the meaning of "eternal life" in scholarly discourse - (1) everlasting life, (2) true, new, and spiritual life, (3) eschatological life of the future age, and (4) resurrected life - the paper highlights the clarity and prominence of the "resurrected life" perspective. Furthermore, it examines whether eternal life is a present reality or a future hope. The majority of scholars support the "present age view," asserting that believers can obtain eternal life in the present while also acknowledging its future dimension, thus presenting a "two-stage view" of eternal life. Finally, the paper addresses the question of how to attain eternal life, emphasizing that in the Gospel of John, "faith" is the sole necessary and sufficient condition. However, this faith is not a superficial belief but a wholehearted commitment to and union with Christ. In summary, through a multidimensional analysis of eternal life, this paper elucidates the rich meaning and significant theological implications of the core message of the Gospel of John: "believing in Jesus to obtain eternal life."
