"By Thy grace, O God, I will go nowhere this day where Thou canst not come, nor court any companionship that would rob me of Thine. By Thy grace I will let no thought enter my heart that might hinder my communion with Thee, nor let any word come from my mouth that is not meant for Thine ear. So shall my courage be firm and my heart be at peace."
John Baillie (1886–1960), Scottish theologian and Church of Scotland minister

This prayer was exactly what I needed as I sit in the Saturday between Good Friday and Easter Sunday extremely discouraged.
