Both of these prayers, I think, are beautiful in their acknowledgment of our human condition and our dependence on Christ in the midst of it. And both are from The Book of Common Prayer, the 2019 edition. May they bless you this night.
“Be present, O merciful God, and protect us through the hours of this night, so that we who are wearied by the changes and chances of this life may rest in your eternal changelessness; through Jesus Christ our Lord. Amen.”
“Keep watch, dear Lord, with those who work, or watch, or weep this night, and give your angels charge over those who sleep. Tend the sick, Lord Christ; give rest to the weary, bless the dying, soothe the suffering, pity the afflicted, shield the joyous; and all for your love’s sake. Amen.”
