About keeping watch over Christ's flock:

Jesus went through all the towns and villages, teaching in their synagogues, preaching the good news of the kingdom and healing every disease and sickness. :When he saw the crowds, he had compassion on them, because they were harassed and helpless, like sheep without a shepherd. :Then he said to his disciples, "The harvest is plentiful but the workers are few. � Just as the Father knows me and I know the Father--and I lay down my life for the sheep. :I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd. � The reason my Father loves me is that I lay down my life--only to take it up again. :For I have not hesitated to proclaim to you the whole will of God. � 

Keep watch over yourselves and all the flock of which the Holy Spirit has made you overseers. Be shepherds of the church of God, which he bought with his own blood. � I know that after I leave, savage wolves will come in among you and will not spare the flock. :To the elders among you, I appeal as a fellow elder, a witness of Christ's sufferings and one who also will share in the glory to be revealed: :Be shepherds of God's flock that is under your care, serving as overseers--not because you must, but because you are willing, as God wants you to be; not greedy for money, but eager to serve; :not lording it over those entrusted to you, but being examples to the flock. � And when the Chief Shepherd appears, you will receive the crown of glory that will never fade away. �
