There is a part of the Bible that has always embarrassed me.
It's that part in Genesis (Gen. 30:37-42) where Jacob has a claim on spotted goats and sheep, and he tricks the livestock into producing mottled offspring by placing spotted posts in front of them when they're mating. That has always embarrassed me, since genetics doesn't work that way, and it seemed Scripture was being undermined a bit here.
But I've been driving a lot lately (I'm in Duluth, Minnesota all this week), listening to David Higbee's Scripture Studies. David points out that the meaning of that story is that Jacob congratulates himself for being clever (as usual), while obviously the mottled offspring are entirely God's work. It's not Jacob's accomplishment; it's God's blessing.
We shield ourselves from the pain and awe of existence by telling ourselves how clever we are and by using our wiles to gimmick situations. But we are entirely dependent on His Divine Mercy.
