John Owen helps us understand that it would have been positively unjust for Christ's death on the cross to be for all people. How? By pointing out the following: It is only just for God to demand one death for a person's sins. Therefore, for the unbelievers who one day will die for their sins at the Judgment, Christ could not also have died for their sins. So, for whom did Jesus die? The elect - only those whom God causes to believe in Christ.
