 by the Good Shepherd, that's being united to God, that's becoming, as Paul says, a new creature and the old things have passed away. It's moving from the broad way to the narrow way that Jesus spoke of and walking that narrow way that leads to life, that place of fellowship now and eternity with God. How does he do it? Notice he says in this same verse, they shall hear my voice. He does it by hearing and by people responding.
