What does the Bible say about Adam as our representative?

In Romans 5:12, Paul explains that 'as by one man, Adam, sin entered into the world and death by sin.' Adam's actions serve as our legal representative, meaning that when he sinned, all of humanity was found guilty in him. His failure to obey God's command led to a sinful nature being passed down to every person born of Adam, as stated in Romans 5:19: 'For as by one man's disobedience many were made sinners.' This underscores the idea that we are not just in a state of potential sin; we have been made sinners by Adam's original transgression.
