Evil people have to pay for all the bad things they do to good people. People who are not honest have to pay for the things they do to honest people.
A good person will escape trouble, and that trouble will happen to some evil person.
Christ himself died for you. And that one death paid for your sins. He was not guilty, but he died for people who are guilty. He did this to bring you all to God. His body was killed, but he was made alive in the spirit.
