It is impossible to do what God’s standards demand because of the weakness our human nature has. But God sent his Son to have a human nature as sinners have and to pay for sin. That way God condemned sin in our corrupt nature.
This is true because Christ suffered for our sins once. He was an innocent person, but he suffered for guilty people so that he could bring you to God. His body was put to death, but he was brought to life through his spirit.
After all, the Good News was told to people like that, although they are now dead. It was told to them so that they could be judged like humans in their earthly lives and live like God in their spiritual lives.
