Psalms 23 is one of the most popular Psalms. The author, David was once a shepherd. He is one of the well-known shepherds in the Bible. David wrote the Psalms when he was a shepherd boy. As a shepherd himself, David can say, “The Lord is my shepherd, I shall not want,” because he understood the Lord was looking after him, providing for him, and protecting him from danger. Similarly, the Lord is our shepherd. He supplies all of our needs. He leads us to green pastures and protects us from danger. He is ever watching over us, even when we do not notice. He cares for our well-being. He is there for us in times of need. He feels our pain, and heals us when we are wounded.

The shepherd

The role of a shepherd is to oversee the flock. It is a job which requires carefulness and tender care. The shepherd leads the sheep to the green pastures and also defends them. Sheep are good followers. They will follow their leader wherever he or she goes. Sheep are prone to wander if they do not have a shepherd. Sheep are prey to other animals and need to be taken care of. By themselves, sheep are meek and defenseless. They will run from danger. The good shepherd will defend the sheep from attack. David is a good shepherd because he looks well after the sheep. He is willing to defend the sheep from other animals. David tells Saul that he fought the lion and the bear and delivered the lamb out of the mouth of the lion. 1 Samuel 17:34-35.

Shepherds witnessed the birth of Christ

Shepherds were among the first people to witness the birth of Christ, the good shepherd. This symbolized that He had come to seek and save humanity. He is the good shepherd who was willing to lay down His life in order to save us. John 10:11. Sheep belong to the shepherd. Jesus is the shepherd who will never abandon the sheep. They are His own. He purchased them with His own blood. Jesus is also known as the Lamb because of His sacrifice on the cross. As Isaiah pointed out, He would be led to the slaughter just like a lamb. Isaiah 53:7. Jesus knows His sheep and they know His voice and they follow Him. 

Jesus the good shepherd

Jesus says He is the good shepherd, "I am the good shepherd. The good shepherd lays down His life for the sheep." John 10:11. He laid down His life for us on the cross so we may be saved. He is the suffering servant predicted by Isaiah. 

He was oppressed, and He was afflicted, yet he opened not His mouth: He is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so He openeth not His mouth. Isaiah 53:7

Jesus cares not only about the sheep in the fold, but the sheep who are not. He will search for them and bring them Himself. John 10:16.

The lost sheep

In the parable of the lost sheep, in Matthew 18:10-14, the shepherd will leave the ninety nine sheep and go searching for the one lost sheep. When he finds it He will rejoice. The Lord will search for the lost sheep. He notices any sheep which has gone astray and makes an effort to bring it back to the fold. He is a good shepherd who cares about each and everyone of us. He knows each of us by name. He cares specifically about each individual.

God is a good shepherd

God is a good shepherd. He came down to us to save us. He will search His sheep who are scattered and will deliver them. 

For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out. Ezekiel 34:11

He will seek the lost sheep and bring them back to the fold. He will bring the sheep which was driven away. He will bind up the broken sheep. He will strengthen the sick. Ezekiel 34:16. God came down to search for the lost sheep. He laid down His life for us. He is a good shepherd and we are sheep. He will search for lost souls and bring them back. 

If God is our shepherd, we shall not want. He will supply all of our needs. He will guide us, even in times of danger. He will not abandon us.We need to trust in the Lord.
