What kind of person would use this tool to do his or her work? A shepherd. What do shepherds take care of? Do you think sheep are easy to take care of? It may surprise you that they are not! They are easily scared, and they need food and water nearby all the time. Sheep also like to explore and find any hole in the fence to escape. Then they might also get lost.
A shepherd with many sheep needs to watch them carefully so that they will not wander away and so that no wolves or other wild animals will attack them. He risks his life to chase away the animal that would hurt his sheep. He needs to lead the sheep to clean water and green grass. He comes to know each sheep by name.
Jesus says, “I am the good shepherd” (John 10:11). He never took care of actual sheep, but He is talking about taking care of us. He knows each of us by name too. He gave his life to save us from our enemies of sin and Satan.
You are my shepherd, I have everything that I need. You lead me. Protect me in times of danger. I am as helpless as a sheep without you.
