Much more then, being now justified by his blood, we shall be saved from wrath through him.

Paul says this, because if God allowed his Son to be killed for sinners’ sake, what will he do for those who have been justified except save them from wrath, that is, preserve them unharmed from the deception of Satan so that they will be safe on the day of judgment, when revenge will begin to destroy the wicked. For since the goodness of God does not want anyone to perish, he has shown mercy on those who deserved death in order to increase the honor and glory of those who understand the grace of God.
