Tyler Staton in Praying Like Monks, Living Like Fools:
Jesus hasn’t revealed a God we can perfectly understand, but he has revealed a God we can perfectly trust. Trust is the certainty that the listening God hears and cares. I trust the God who, even when he doesn’t make the suffering go away, wears the suffering alongside me. Trusting the God revealed in Jesus means silence is real, but it’s not forever.
I associate the phrase si comprehendis non est deus with Augustine. Any god that we imagine we “perfectly understand” is something other than the real God depicted in the Bible. Such a god is merely an idol. We have plenty of idols available these days, even (particularly?) in the church.
