'God's in His Heaven, all's right with the world,' Robert Browning wrote, and the psalm is not saying that any more than you or I can say it either. Whoever wrote it had walked through the valley of the shadow the way one way or another you and I have walked there too. He says so himself. He believed that God was in his Heaven despite the fact that he knew as well as we do that all was far from right with the world. And he believed that God was like a shepherd.
When I think of shepherds, I think of one man in particular I know who used to keep sheep here in Rupert a few years back. Some of them he gave names to, and some of them he didn't, but he knew then equally well either way. If one of them got lost, he didn't have a moment's peace till he found it again. If one of them got sick or hurt, he would move Heaven and earth to get it well again. He would feed them out of a bottle when they were new-born lambs if for some reason the mother wasn't around or wouldn't 'own' them, as he put it. He always called them in at the end of the day so the wild dogs wouldn't get them. I've seen him wade through snow up to his knees with a bale of hay in each hand to feed them on bitter cold winter evenings, shaking it out and putting it in the manger. I've stood with him in their shed with a forty watt bulb hanging down from the low ceiling to light up their timid, greedy, foolish, half holy faces as they pushed and butted each other to get at it because if God is like a shepherd, there are more than just a few ways, needless to say, that people like you and me are like sheep. Being timid, greedy, foolish, and half holy is only part of it.
Like sheep we get hungry, and hungry for more than just food. We get thirsty for more than just drink. Our souls get hungry and thirsty; in fact it is often that sense of inner emptiness that makes us know we have souls in the first place. There is nothing that the world has to give us, there is nothing that we have to give to each other even, that ever quite fills them. But once in a while that inner emptiness is filled even so. That is part of what the psalm means by saying that God is like a shepherd, I think. It means that, like a shepherd, he feeds us. He feeds that part of us which is hungriest and most in need of feeding.
