Many priests, religious, and laity through the centuries have known the power of "waiting an hour" with The Lord present in the Most Blessed Sacrament. As you go before Jesus present in the tabernacle or in the monstrance upon the altar, here are some suggestions to aid your time in prayer:
Fr. Benedict Groeschel points out in the book, "In the Presence of Our Lord : The History, Theology and Psychology of Eucharistic Devotion" that there are "four kinds of prayer most appropriate in the presence of the Eucharist, namely adoration and praise, thanksgiving, repentance and trusting intercession."
Say "Lord Jesus, have mercy on me, a sinner", repeatedly as you quiet your heart and mind.
Choose a passage from the Bible. read the words and ask God to let the passage speak to you. Pay special attention to anything that strikes you and ask God what He wishes for you to draw from that message. Be patient and ask for the grace to be okay with Holy Silence.
by St. Faustina
Speak to Jesus, aware that you are in His presence, and tell Him all that comes to your mind. Listen for His response. Pray the prayer that St. Francis instructed his brothers to pray whenever they were before the Blessed Sacrament: "I adore You, O Christ, present here and in all the churches of the world, for by Your holy cross You have redeemed the world."
I adore You, Lord and Creator, hidden in the Most Blessed Sacrament. I adore You for all the works of Your hands, that reveal to me so much wisdom, goodness and mercy, O Lord. You have spread so much beauty over the earth and it tells me about Your beauty, even though these beautiful things are but a faint reflection of You, incomprehensible Beauty. And although You have hidden Yourself and concealed Your beauty, my eye, enlightened by faith, reaches You and my soul recognizes its Creator, its Highest Good, and my heart is completely immersed in prayer of adoration.
My Lord and Creator, Your goodness encourages me to converse with You. Your mercy abolishes the chasm which separates the Creator from the creature. To converse with You, O Lord, is the delight of my heart. In You I find everything that my heart could desire. Here, Your light illumines my mind, enabling it to know You more and more deeply. Here streams of graces flow down upon my heart. Here my soul draws eternal life. O my Lord and Creator, You alone, beyond all these gifts, give Your own self to me and unite Yourself intimately with Your miserable creature.
O Christ, let my greatest delight be to see You loved and Your praise and glory proclaimed, especially the honor of Your mercy. O Christ, let me glorify Your goodness and mercy to the last moment of my life, with every drop of my blood and every beat of my heart. Would that I be transformed into a hymn of adoration of You. When I find myself on my deathbed, may the last beat of my heart be a loving hymn glorifying Your unfathomable mercy. Amen.
