....”Jesus Christ, our Shepherd Whose voice we recognize and respond to”....
I like this equation very much....of course it’s really much deeper then this ...
“My sheep hear my voice, and I know them” = mutual recognition.
“They follow me, and I give them eternal life” = reciprocal activity.
“They shall not perish forever, and no one shall pluck them out of my hand” = an authoritative assurance.
