Jesus points out that good shepherds, good leaders, willingly lay down their LIFE for their sheep. False shepherds, bad leaders, are too busy looking out for themselves to lay down their life for their sheep. I have authority to lay it down and authority to take it up again. You know that He went on to give His life for you and for me on the Cross of Calvary. Good shepherds are like that.
Good leaders go out in front of their following.
They don't stay behind where it's safe. They don't make the flock face what they themselves are not willing to face. The wolf attacks the flock and it scatters. The false leader runs away because he or she cares nothing for the sheep. The false shepherd, the bad leader is characterized by a lack of commitment to the sheep.
