For none of us lives to himself, and no man dies to himself.
Read Chapter 14
Ambrosiaster
AD 400
A man would be living for himself if he did not act according to the law. But whoever is controlled by the brake of the law is not living for himself but for God, who gave the law so that it might be possible to live according to his will. Likewise, whoever dies dies to God, for he is the Judge who will either condemn or reward him. Commentary on Paul’s Epistles.
This means that we are not free. We have a master who wants us to live and not die, and to whom life and death matter more than they do to us…. For if we die, we do not die to ourselves alone but to our master as well. By “death,” Paul means apostasy from the faith.
