Romans 5:12, 18

When Adam sinned, the entire world was affected. Sin entered human experience, and death was the result. And so death followed this sin, casting its shadow over all humanity, because all have sinned.

In other words, just as condemnation came upon all people through one transgression, so through one righteous act of Jesus’ sacrifice, the perfect righteousness that makes us right with God and leads us to a victorious life is now available to all.
