The voice we follow matters. Jesus offers us an opportunity to discern between himself and the alternative(s). Only he is the Good Shepherd and this can be known because he lays down his life to death for us, to protect us from death. The other voices are only pale imitations of the Good Shepherd. They may bear a resemblance to a shepherd but the truth is at the first sign of danger which they lead us to they will abandon us to death. Whose your shepherd?
