"The way to fulfill the law, the way to live the way God intends for us to live," Paul says, "is to love."
Krister Stendhal, in his Final Account, Paul's Letter to the Romans, reminds us that church people in particular may need to hear this command to love one another:
"Knowledge puffs up, and love builds up, and Paul is not using that language in order to say that there is much love in the church. On the contrary, he said, if you are going to be a church, and if you are going to be able to stand such distressing fellow Christians as we Christians often are to one another, and as we find ourselves to be, you surely need love. Love is measured by the amount of tension it can take, not by how it feels."
