We also recall the agony of Jesus in the first decade of the sorrowful mysteries of the rosary, and on the eve of each first Friday of the month.
When we recall what Jesus endured on this night before His sorrowful Passion it is natural for us to want to do something in return for such great love. An easy way to do this is to remain in prayer at the Altar of Repose at the conclusion of the Holy Thursday night Mass. Staying for at least an hour in prayer can be our personal way of responding to the sad words of Jesus to Peter in Matt 26:40, 'So you had not the strength to keep awake with Me one hour?'.
St Padre Pio had a particular devotion to the Agony of Jesus in the Garden, as had St Gemma Galgani and Blessed Elena Guerra. There are some spiritual gifts and graces that only come from meditating upon this part of the passion of Jesus.
You might find this little booklet (downloadable below) useful in your prayers and meditations on the Agony of Jesus. It will take 3 sheets of double-sided A4 paper in booklet fold to print.

One way of using it is to read one line at a time, and then talk to Jesus in your heart about it. Another way is to read a full passage or paragraph, and then to slowly pray a few Glory Bes or Hail Marys between them.
But the main thing is to pray.
St Peter, St John and St James, Apostles, please pray for us, that our love for Jesus in His Agony may grow.
St Padre Pio, St Gemma Galgani, Bl Elena Guerra, pray for us that we may develop a true devotion to the Agony of Jesus in our lives.
