Our need for the Good Shepherd, and for good shepherds:

And Jesus went about all the cities and villages, teaching in their synagogues and preaching the gospel of the kingdom, and healing every disease and every infirmity.  When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd.  Then he said to his disciples, “The harvest is plentiful, but the laborers are few; pray therefore the Lord of the harvest to send out laborers into his harvest*.”

(*Pentecost was a harvest celebration.  The Lord indeed sent laborers into His harvest after Pentecost.)

And he called to him his twelve disciples and gave them authority over unclean spirits, to cast them out, and to heal every disease and every infirmity.  The names of the twelve apostles are these:  first, Simon, who is called Peter, and Andrew his brother; James the son of Zebedee, and John his brother; Philip and Bartholomew; Thomas and Matthew the tax collector; James the son of Alphaeus, and Thaddaeus; Simon the Cananaean, and Judas Iscariot, who betrayed him.

These twelve Jesus sent out, charging them, “Go nowhere among the Gentiles, and enter no town of the Samaritans, but go rather to the lost sheep of the house of Israel. …

“Behold, I send you out as sheep in the midst of wolves; so be wise as serpents and innocent as doves.”  (Matthew 9:35-10:5, 10:16)

These good shepherds MUST trust completely in the one Good Shepherd and follow Him since they are, after all, sheep themselves “in the midst of wolves.”
