The beauty of Psalm 23 is that it is so simple and clear that it almost needs no interpretation or exposition. It is short, easily memorized, and it has poetic images and a lyrical tilt which has lodged this song in the collective consciousness of every believer through the ages. But when you unload the metaphor of the Lord as our shepherd within the psalm, then the riches of all its verses shine all the brighter.

The Lord is my shepherd; I shall not want.—Psalm 23:1

God as Shepherd

If you had a blank canvas to sketch a single picture of Israel’s exodus from slavery, what would you draw? The picture in your mind’s eye is possibly not the one the Bible depicts.

Psalm 77 portrays God’s redemption of his people from Egypt in this way:

Your way was through the sea,
your path through the great waters;
yet your footprints were unseen.
You led your people like a flock
by the hand of Moses and Aaron. —Ps. 77:19–2

Observe the imagery in Psalm 78 as well:

He struck down every firstborn in Egypt,
The firstfruits of their strength in the tents of Ham.
Then he led out his people like sheep
and guided them in the wilderness like a flock.
He led them in safety, so that they were not afraid,
but the sea overwhelmed their enemies.—Ps 78:51–53

So when the Bible puts the exodus, the great event of Israel’s redemption, on Instagram what do we see? A divine shepherd leading his flock of under-shepherds and sheep through terrible danger to complete safety. God is a shepherd.

What kind of shepherd is he?

All-Powerful God

God’s rescue of his people in the book of Exodus is preceded by his revelation of his name to Moses at the burning bush. “God said to Moses, ‘I am who I am.’ And he said, ‘Say this to the people of Israel: ‘I am has sent me to you’” (Ex. 3:14). This unusual rendering of the Hebrew verb “to be” points to “One who remains constant because he is independent.”1 God is who he is without us. He is who is from before we were until after we have been. God’s existence is from himself and for himself, and there is nothing about him derived from anyone or anything else. He is absolutely self-sufficient self-existence.

This is illustrated by the burning bush where Moses encounters God. As Sinclair Ferguson says, “The fire that was in the bush was not dependent on the bush for its energy to burn. It was a most pure fire, a fire that was nothing but fire, a fire that was not a compound of other energy sources but had its energy source in itself.”2There is such wonderful beauty here that it is worth just lingering over this. Consider these words of Alexander Maclaren:

The fire that burns and does not burn out, which has no tendency to destruction in its very energy, and is not consumed by its own activity, is surely a symbol of the One Being, whose being derives its law and its source from itself, who can only say—“I am that I am” —the law of his nature, the foundation of his being, the only conditions of his existence being, as it were, enclosed within the limits of his own nature. You and I have to say, “I am that which I have become,” or “I am that which I was born,” or “I am that which circumstances have made me.” He said, “I am that I am.” All other creatures are links; this is the staple from which they all hang. All other being is derived, and therefore limited and changeful; this being is underived, absolute, self-dependent, and therefore unalterable forevermore. Because we live, we die. In living, the process is going on of which death is the end. But God lives forevermore. A flame that does not burn out; therefore his resources are inexhaustible, his power unwearied. He needs no rest for the recuperation of wasted energy. His gifts diminish not the store which he has to bestow. He gives and is none the poorer. He works and is never weary. He operates unspent; he loves and he loves forever. And through the ages, the fire burns on, unconsumed and undecayed.3

Doesn’t this help us see how incredible it is that the Lord should be our shepherd? I believe the point of this revelation of who God is to Moses was precisely to assure him that the impossible was about to happen for God’s people in Egypt, because the infinite, eternal God had come to lead them home. It is because of who God is that the exodus happens at all and why it succeeds. He is the all-powerful One.
