"They were like sheep without a shepherd." Mt. 6, 34
A shepherd does these among other things for his sheep. He feeds them. In doing so, he looks for the best place for his sheep to feed. The shepherd provides for all the things needed by his sheep.
The shepherd defends his sheep. He fights for them against the wild animals and thieves who want to harm his sheep.
The shepherd looks for his lost sheep. He goes after them when the sheep will wander from the flock.
The shepherd then provides for his sheep. He defends them. He looks for them.
So our God does these to us. He provides for everything we need. He defends us from the evil one. He looks for us when we are lost. We need only to trust in Jesus, our Shepherd. We listen to His voice. We follow His commands. We obey His will.
