How do we know the end of all things is true?

The assertion that 'the end of all things is at hand' is anchored in the Christian understanding of divine revelation. Peter communicates this truth as a faithful saying, echoing the prophetic nature of Scripture that assures believers of the reality of Christ's return and the consummation of His Kingdom. This is corroborated by other Scriptures that urge believers to remain vigilant and to conduct themselves accordingly, acknowledging that earthly life is fleeting, like a vapor (James 4:14). Therefore, the certainty of this statement is part of the Christian faith, one that believers are called to proclaim as part of their witness in a transient world.
