Ability to separate the Sheep;

When it becomes necessary to separate several flocks of sheep, one shepherd after another will stand up and call out: Tahhoo! Tahhoo! or a similar call of his own choosing. The sheep lift up their heads, and after a general scramble, begin following each one his own shepherd. They are thoroughly familiar with their own shepherd’s tone of voice. Strangers have often used the same call but their attempts to get the sheep to follow them always fail. The words of Jesus are indeed true to Eastern Shepherd life when he said: “The sheep follow him, for they know his voice. A stranger they will not follow, but they will flee from him, for they do not know the voice of strangers.” (John 10:4,5)

I want to be a lamb that only follows my shepherd (Jesus) and knows His true voice amongst all the noise of false voices.
