How do we know future retribution for sin is true?

The reality of future retribution for sin is a fundamental tenet of Christian doctrine, grounded in the teachings of Scripture. Passages like Luke 16:25 illuminate the seriousness of this concept, where the rich man in torment recalls his previous life and the choices he made. This underscores the biblical teaching that God will one day require an account of every thought and deed. The impending justice of God serves as both a warning and a call to repentance, reminding us that the consequences of sin are serious and eternal, meant to provoke a sincere reflection in the hearts of believers and unbelievers alike.
