My brother’s keeper? Yeah, maybe. My cousin’s keeper? Probably not so much. My third cousin twice removed’s barber’s ex-wife’s auto mechanic who snuck in from Guadalajara so he could peddle fentanyl to junior high kids? Probably not at all.
That would mean each US Christian is to be the keeper of every person in the world, or at least, every random one that decides to wander over into our borders at any particular moment. Nope, I can’t be responsible for millions of people. God surely would not ask such a thing lol.
