Mike found In Sorrow's Lone Hour, by Clement H. Pugsley
while we were browsing the book section of a
thrift shop recently.
Here is a prayer from the chapter called Further Prayers for the Dark Hour which seems to be a beautiful multi-purpose prayer:
"O Lord God, in Whom we live, and move, and have our being, open our eyes that we may behold Thy Fatherly presence ever about us. Draw our hearts to Thee with the power of Thy love. Teach us to be anxious for nothing, and when we have done what Thou hast given us to do, help us, O God our Saviour, to leave the issue to Thy wisdom. Take from us all doubt and mistrust. Lift our thoughts up to Thee in heaven, and make us to know that all things are possible to us through Thy Son our Redeemer. Amen." Bishop Westcott
