In this engaging exploration of the prayer of our Lord Jesus Christ as recounted in the seventeenth chapter of St. John, I am excited to present my homilies that delve into its profound meanings. With the help of my dear friend, M. Caspar Cruciger, who graciously took on the task of organizing these insights, I aim to share this valuable reflection with fellow Christians who yearn for spiritual nourishment. I hope these thoughts serve as a refreshing source of encouragement for those who thirst for righteousness.
