If you go over to Scotland, or anywhere there are lots of sheep, sooner or later you're going to see a very unusual sight. You'll see a little lamb running around the field, and you'll notice this lamb has what looks like an extra fleece tied around its back. In fact, you'll see there are little holes in the fleece for its four legs and usually a hole for its head. If you see a little lamb running around like that, that usually means its mother has died.

And without the protection and nourishment of a mother, any orphaned lamb will die. If you take the orphaned lamb and try to introduce it to another mother, the new mother will butt it away. She won't recognize the lamb's scent and will know the new baby is not one of her own lambs.

But thankfully, most flocks are large enough that there is a ewe that has recently lost a lamb. The shepherd will skin the dead lamb and make its fleece into a covering for the orphaned lamb, then he'll take the orphaned lamb to the mother whose baby just died. Now, when she sniffs the orphaned lamb, she will smell the fleece of her own lamb. Instead of butting the lamb away, she will accept it as one of her own.

In a similar way, we have become acceptable to God by being clothed with Christ.
