“ You can't reconcile being pro-life on abortion and pro-death on the death penalty. ”
Caesar's messengers didn't go round the world saying, 'Caesar is lord, so if you feel you need to have a Roman-empire kind of experience, you might want to submit to him'.
~ N. T. Wright
If what we want is God’s justice, coming to sort things out, we will do better to get entirely out of the way and let God do his own work, rather than supposing our burst of anger (which will most likely have all sorts of nasty bits to it, such as wounded pride, malice and envy) will somehow help God do what needs to be done.
Most of the things that really matter require faith. 'How do I know that my wife loves me?' 'How do I know that Mozart's 'Jupiter Symphony' is sublime and beautiful?' There are all sorts of things which come at a more lowly level than that - 'How do I know that two plus two equals four?' There are different layers, different types of knowing.
Within orthodoxy, there is always a danger of faith collapsing into fear.
