Garden-variety sinners do that. I tell you, love your enemies. Help and give without expecting a return. Live out this God-created identity the way our Father lives toward us, generously and graciously, even when we're at our worst. Giving, not getting, is the way.

Jesus offered an economy of mercy that extends to all, especially the outsiders, including Israel's enemies. The only way this section ought to be read is quite slowly, letting it sink in, drop by drop, phrase by phrase. As we neither rush toward these words nor push them away, in the quiet, an image will eventually come forward to show us what happens within us as we love our enemy. It probably needs to be appended here. These great injunctions, without implementation, are less than helpful.
