If we are commanded to love sacrificially, does that mean we cannot draw boundaries?

I’ll start with my own wondering about how we define sacrificial love.  Too often, we think about love as just doing the thing that feels best in the moment or that will make the person in front of us feel better.  In other words, we are measuring by our feeling or by the other person’s reaction. This kind of loving is exhausting and we often end up pouring out more and more.  In contrast, the commandment to love measures according to the love we have received from God- it is a love that challenges, comforts, clarifies, and holds accountable.  Knowing we are deeply loved by God transforms our interactions with God and our neighbors.
