These my homilies concerning the prayer of our Lord Jesus Christ, which St. John has delivered down to us in his seventeenth chapter, I not only saw with pleasure printed and brought forth into public, but myself requested my particular friend, M. Caspar Cruciger, to undertake the labour of collecting them and reducing them into a regular form, (for I had not time and leisure to do it myself) that he might put them into the hands of others. For I was fully persuaded, that this crumb and this cup. of cold water would be useful and acceptable unto godly Christians who hunger and thirst after righteousness; whom alone I desire to serve in these labours.
