Now I have something to tell your elders: I am an elder myself, and a witness to the sufferings of Christ, and with you I have a share in the glory that is to be revealed. Be the shepherds of the flock of God that is entrusted to you: watch over it, not simply as a duty but gladly, because God wants it; not for sordid money, but because you are eager to do it. Never be a dictator over any group that is put in your charge, but be an example that the whole flock can follow. When the chief shepherd appears, you will be given the crown of unfading glory.

Here I am, Lord! I come to do your will.

I waited, I waited for the Lord
  and he stooped down to me;
  he heard my cry.

Here I am, Lord! I come to do your will.

He put a new song into my mouth,
  praise of our God.
Many shall see and fear
  and shall trust in the Lord.

Here I am, Lord! I come to do your will.

You do not ask for sacrifice and offerings,
  but an open ear.
You do not ask for holocaust and victim.
  Instead, here am I.

Here I am, Lord! I come to do your will.

In the scroll of the book it stands written
  that I should do your will.
My God, I delight in your law
  in the depth of my heart.

Here I am, Lord! I come to do your will.

Your justice I have proclaimed
  in the great assembly.
My lips I have not sealed;
  you know it, O Lord.

Here I am, Lord! I come to do your will.

Alleluia, alleluia!
I call you friends, says the Lord,
because I have made known to you
everything I have learnt from my Father.
Alleluia!
