One of the blogs I subscribe to posted this Good Friday prayer this morning:
O Savior of the world, who by Your cross and precious blood has redeemed us: save us and help us, we humbly ask You, O Lord. Forbid, O God, that we should forget, amid our earthly comforts, the pains and mortal anguish that our Lord Jesus endured for our salvation. Grant us this day a true vision of all that He suffered, in his betrayal, His lonely agony, His false trial, His mocking and scourging, and the torture of death upon the cross. As you have graciously given yourself utterly for us, may we give ourselves entirely to you, O Jesus Christ, our only Lord and Savior. AMEN
I thought its brevity and poignancy was stirring. You can find the blog where it originates here.
