A good shepherd will not allow any of his sheep to be harmed. Someone who is paid to keep sheep or is just tending the flock for his own benefit might run from the dangers and leave the sheep alone. David was an example of a good shepherd, he fought the bear and the lion and literally took the sheep from their mouth.
34 But David said to Saul, “I, your servant, have been keeping my father’s sheep. When a lion or bear came and took a sheep from the flock, 35 I would chase it. I would attack it and save the sheep from its mouth. When it attacked me, I caught it by its fur and hit it and killed it. –1 Samuel 17:34-35 (NCV)
Jesus is a better shepherd than David. He loved us so much that He gave up His glory in heaven to come to earth so that we could be redeemed. He became human and dwelt among us. He came so that we would know His voice and choose to follow Him. He died to redeem and reconcile us to God. He is still in the reconciliation business. He fights every battle for us and yes, He even pulls some of us from the mouth of hell. Jesus hates the sin but loves the sinner. He expects us to have that same attitude. There are those God has put in our paths that He has chosen for us to shepherd. Be a good shepherd and love them into the fold just as Jesus did for us.
22 Show mercy to some people who have doubts. 23 Take others out of the fire, and save them. Show mercy mixed with fear to others, hating even their clothes which are dirty from sin—Jude 22 (NCV)
