I must admit, I do not know the compete context of this picture, but the actions taking place speaks to my heart. This is love. The bible tells us the only debt we should carry is that of love. (Rom 13:9)
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. Matthew Henry's commentary puts it this way, "He that loves his neighbor as himself, will desire the welfare of his neighbor. On this is built that golden rule, of doing as we would be done by. Love is a living, active principle of obedience to the whole law. Let us not only avoid injuries to the persons, connections, property, and characters of men; but do no kind or degree of evil to any man, and study to be useful in every station of life."
