Change what a man believes he is and his behavior reorganizes itself, with no willpower spent holding the line.
The strongest pull in a person is the need to act consistently with how they define themselves, and that pull will overrule appetite, fear, and even a son's grief. A consecration to God carried on the head is a definition, not a restraint, and the definition decides what is available to do before loss arrives.
Grief tests a label harder than anything, because every reason stands on its side. A man holding only a rule argues with himself there and loses. A man whose separation to God is what he is pays a real price: he gives up the right to reopen the question each time it costs him something.
