Do not leave any debt unpaid. Your only continual obligation is to love one another, because doing so fulfills all that God’s law requires.

Romans 13:8-10

8 Pay all of your debts when you are supposed to pay them. The only thing that is like a debt that you should never stop paying is to love one another. Whoever loves others has fulfilled all that God requires in his laws. 9 There are many things that God commanded in his laws, such as do not commit adultery, do not murder anyone, do not steal, and do not desire anything that belongs to someone else. But the command by which they are all summed up {that includes them all} is this: Each of you must love the people with whom you come in contact, just like you (sg) love yourself. 10 If you love people with whom you come in contact [PRS], you will not do any evil to them [LIT]. So, whoever loves others fulfills all that God’s laws require.
