In the parable of the persistent widow (Luke 18:1-8), a poor, powerless person (the widow) persists in nagging a corrupt, powerful person (the judge) to do justice for her. The parable assumes John the Baptist’s teaching that holding a position of power and leadership obligates you to work justly, especially on behalf of the poor and weak. But Jesus focuses the parable on a different point, that we are “to pray always and to not lose heart” (Luke 18:1). He identifies the hearers — us — with the woman, and the prayed-to person — God — with the corrupt judge, a strange combination. Assuming that Jesus doesn’t mean that God is corrupt, the point must be that if persistence pays off with a corrupt human of limited power, how much more will it pay off with a just God of infinite power.
The purpose of the parable is to encourage Christians to persevere in their faith against all odds. But it also has two applications for those who work in positions of leadership. First, the juxtaposition of a corrupt judge with a just God implies that God’s will is at work even in a corrupt world. The judge’s job is to do justice, and by God, he will do justice by the time the widow is finished with him. Elsewhere, the Bible teaches that the civil authorities serve by God’s authorization, whether they acknowledge it or not (John 19:11; Romans 13:1; 1 Peter 2:13). So there is hope that even in the midst of systemic injustice, justice may be done. A Christian leader’s job is to work toward that hope at all times. We cannot right every wrong in the world in our lifetimes. But we must never give up hope, and never stop working for the greater good in the midst of the imperfect systems where our work occurs. Legislators, for example, seldom have a choice of voting for a good bill versus a bad bill. Usually the best they can do is to vote for bills that do more good than bad. But they must continually look for opportunities to bring bills to a vote that do even less harm and even more good.
The second point is that only God can bring about justice in a corrupt world. That is why we must pray and not give up in our work. God can bring miraculous justice in a corrupt world, just as God can bring miraculous healing in a sick world. Suddenly, the Berlin wall opens, the apartheid regime crumbles, peace breaks out. In the parable of the persistent widow, God does not intervene. The widow’s persistence alone leads the judge to act justly. But Jesus indicates that God is the unseen actor. “Will not God grant justice for his chosen ones who cry to him day and night?” (Luke 18:7).
The use of the term “greater good” implies that the consequences of our actions are important in Christian ethics. This mode of ethical thinking, called “consequentialism,” may be unfamiliar to those who are used to thinking of the Bible only in terms of ethical rules. However, the Bible makes use of all three modes of ethical reasoning that have been identified over the centuries: rules, consequences and virtues. By no means does this make the Bible “relativistic” or “utilitarian,” to name two ethical systems that truly are foreign to biblical thinking.
