Final answer:
Christ's reign is believed to be eternal based on biblical references.
Step-by-step explanation:
The duration of Christ's reign as described in religious texts is a topic related to theology and eschatology, rather than an ascertainable historical timeline. Scriptural passages from the Christian Bible, notably within the New Testament, contain various symbolic narratives and prophetic descriptions concerning the reign of Christ and the end times. For instance, Revelation 20:4-6 hints at a reign of a thousand years, however, interpretations of this 'Millennial Kingdom' vary among different Christian denominations. The concept of an eternal reign is more theological and symbolic, indicating Christ's perpetual sovereignty in the spiritual realm rather than a measurable period in temporal terms.
The quote provided does not give explicit information about the length of Christ's rule but mentions a belief about a significant event where Christ lays down the 'yoke' he bore for humanity's sins. This is not a typical theological view and seems to be part of a personal revelation or interpretation. Mainstream Christian doctrine suggests that Christ's sacrificial role and reign are ongoing, transcending human measures of time.
