Avoid getting into debt, except the debt of mutual love. If you love your fellow men you have carried out your obligations. Love is the one thing that cannot hurt your neighbor; that is why it is the answer to every one of the commandments.
Romans 13:8 (NLT)
8 Owe nothing to anyone—except for your obligation to love one another. If you love your neighbor, you will fulfill the requirements of God’s law.
Romans 13:10 (NLT)
10 Love does no wrong to others, so love fulfills the requirements of God’s law.
