The correct quotation is,"Though the mills of God grind slowly, yet they grind exceeding small; Though with patience stands He waiting, with exactness grinds He all." In other words, God (and therefore, Justice) may take a long time to occur, nevertheless, it will happen. An Elder in the Mormon faith stated "God doesn't balance His books in October", which is a from a story about a rich, but wicked man who had a full harvest, and barns full of grain. While he was prosperous, many good people were poor and hungry. When a boy asked his father why he should be good, when goodness hadn't helped them to be rich, or even comfortable--and the worst man they knew was doing so well at the harvest, (October) the father simply replied, "Son, God doesn't balance His books in October.) This is the essence of justice waiting for God to enact it. Some faiths call it Karma. (One of my favorites is "Nobody gets out of this life alive; we're all sentenced to what we deserve.) Justice delayed is NOT justice denied; it's just delayed. And there will be justice.
