But they were not spiritually hearing Him, because they were not of His sheep. The “knowing” of Jesus Christ occurs in the spirit, when His sheep hear his “voice” then Christ “knows” them. Therein is the direct Spiritual revelation that Jesus Christ is Lord!Amen!
"My sheep hear my voice, and I know them, and they follow me" -- John 10:27
His sheep follow Him because He knows them, because He has loved them from before the foundation fo the world.
