" God takes care of us; he thinks of us every minute, and he gives us instructions that are sometimes very precise. Those surges of love that flow into our chests and take our breath away -- those illuminations, those ecstasies, inexplicable if we consider our biological nature, our status as simple primates-- are extremely clear signs.

And today I understand Christ's point of view and his repeated horror at the hardening of people's hearts: all of these things are signs, and they don't realise it. Must I really, on top of everything else, give my life for these wretches? Do I really have to be explicit on that point?

Apparently so. "
