What does the Bible say about sin and death?

The Scriptures clearly indicate that sin came into the world through one man, Adam, and as a result, death spread to all men because all have sinned (Romans 5:12). Joseph’s death, as mentioned in Genesis 50:26, serves as a sobering reminder of humanity's mortality. The narrative of the Bible from Genesis to Revelation consistently shows that all of humanity is affected by this original sin, and thus we are all sinners by nature and action, unable to achieve righteousness on our own. The law was given to reveal this truth, highlighting our inability to heal ourselves and driving us to seek salvation in Christ alone.
