Who willingly sells himself as a slave? Proverbs says that anyone who owes a debt is like a slave to the lender, and yet the more we pay on a debt of love, the more we owe on it. We aren't expected or encouraged to even attempt to actually pay it off. I certainly wouldn't want my mortgage to increase in proportion to the amount I pay on it, yet love works on a different economic system. Often those who are the most wealthy in love from others also "owe" the most, since love is by its nature reciprocal. If we pay out love without receiving payment in return from a particular person, we know that the Lord Himself will repay us. The more we pay, the more we owe; yet also the more we receive, whether from the person we are giving love to or from the Lord of Love. The more we pay and the more we owe, the more wealthy we are in love.
