Christians around the world call this Friday "Good" because of Jesus - his suffering and sacrifice for humankind.
Many will offer to God a prayer like the following, adapted from the Book of Common Prayer:
"Almighty God, we pray you graciously to behold the crowds, for whom our Lord Jesus Christ was willing to be betrayed, and given into the hands of sinners, and to suffer death upon the cross. Behold them - and us - and draw us once more into the life that Jesus poured out through his suffering, who now lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen."
I was in that crowd, as were you, the crowd for whom he was willing to suffer betrayal and crucifixion.
"Thank you, Jesus, for your willingness...for all you suffered...for your total surrender...for the life of the world. Amen."
How will you observe Good Friday today? Holy Saturday tomorrow?
