How do we know that all humans are guilty before God?

In Romans 2:11, we learn that there is no partiality with God, meaning every person, Jew or Gentile, is accountable for their sin. This concept is deeply rooted in the doctrine of total depravity which states that because of Adam's fall, all humanity is born with a sinful nature. Scriptures like Romans 3:23 clearly affirm that all have sinned and lack the glory of God, highlighting the universal need for salvation through Christ. Sovereign grace theology teaches that only through God's grace can anyone be redeemed from this state of guilt.
