Answer:
The sheep tell the difference between a stranger and the Good Shepherd by his voice.
Step-by-step explanation:
The parable of the Good Shepherd and his sheep is seen in the book of John chapter 10 in the New Testament of the Holy Bible. This parable was used by Christ to talk about the believers/ born-again Christians and those who are not. He used this parable to give an example of how a good Christian is supposed to live and follow in the steps of his master.
John chapter 10:1-18 talks about the parable of the Good Shepherd and his sheep who recognize their master's voice. Verse 3-5 says "The gatekeeper opens the gate for him, and the sheep listen to his voice. He calls his own sheep by name and leads them out. When he has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice. But they will never follow a stranger; in fact, they will run away from him because they do not recognize a stranger’s voice".
