The voice of Jesus

John 10:1-10
I tell you the truth, the man who does not enter the sheep pen by the gate, but climbs in by some other way, is a thief and a robber.
Sheep will never follow a stranger, they will run away from him because they do not recognize a stranger'a voice.
Jesus said , "I am the gate for sheep. All who ever came before me were thieves and robbers, but the sheep did not listen to them. I am the gate; whoever enters through me will be saved.
I have come that they may have life, and have it to the full.
Why?
Jesus is the only way to have life, and the life will be full.
God's sheep listen to the shepherd. Shepherd spent  much of his life with his flock, guarded them from wild animals by lying across the entrance to the sheepfold at night. So Jesus said I am the gate.
How?
Am I listen to the voice of Jesus? Do I recognize the voice of Jesus?
