Formerly, when you did not know God, you were slaves to those who by nature are not gods. But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable principles? Do you wish to be enslaved by them all over again? (Galatians 4:8-9)
There is a lovely tension in Christian epistemology between our ‘knowing God’ and being known by God (both of which, to be clear, are about an interpersonal kind of knowledge, not about simply knowing an infinite quantity of ‘facts’ about God or us). One of the central announcements of the NT is that Jesus has revealed God in not only a fresh, unexpected way, but also in a full (and thus final) way. God can at last be known.
But this knowledge of God in the face of Christ does not catapult humans into a state of omniscience. “Who has known the mind of the Lord?”, asks Scripture elsewhere. And in the passage above, Paul suggests that the point is not our knowledge of God, but God’s knowledge of us that matters.
There is continuity and discontinuity here with the knowledge proper to the natural sciences. Continuity in that in both cases, reality often has to surprise us for us to ‘get it’. It’s often not what we expected it to be. Truth has that ring to it. But it also has discontinuity in the obvious sense that nature does not and cannot ‘know us’ as we know one another – let alone as we can be known by God.
