A common misinterpretation views this verse as a promise of immediate immortality or no premature deaths in the present age, ignoring its prophetic context within the new creation; others erroneously apply it to the millennial kingdom to predict literal 100-year childhoods or exclude all infant mortality today, overlooking the hyperbolic language illustrating extraordinary longevity and the persistent reality of sin's curse until final redemption; some dispensationalists rigidly timeline it to a future earthly reign, missing its broader eschatological hope of eternal renewal.
Isaiah 65:20
King James Version (1769)
20 There shall be no more thence an infant of days, nor an old man that hath not filled his days: for the child shall die an hundred years old; but the sinner being an hundred years old shall be accursed.
Isaiah 65:20 envisions the glorious future new heavens and new earth where human lifespan is dramatically extended, such that dying at 100 years old is likened to an infant's death, emphasizing abundant life and vitality as a hallmark of God's renewed creation, yet underscoring that true blessing belongs only to the righteous while sinners, even if long-lived, remain under curse, highlighting the ultimate triumph of justice and holiness in God's kingdom.
