G.K. Chesterton said, “I find it amazing that moderns reject the notion of the doctrine of original sin when it’s the only Christian doctrine that can be empirically verified.”
Sin can be divided into categories of original and actual sin. Original sin refers to the fact all people after the fall of Adam are born in a sinful condition. Mankind inherited Adams guilt and corruption from after his fall into sin. Sadly we have a natural disposition to sin. Actual sin refers to the literal acts of sin we commit that proceed from original sin.
The person who is unpardoned by God from their sin will face His wrath against sin. God has acted to restore sinful people by providing the Savior Jesus Christ. Our duty is to repent of our sin and submit ourselves to Jesus Christ as Lord.
