The seed is in the ground.
Now may we rest in hope
While the darkness does its work.
(Wendell Berry. A Timbered Choir: The Sabbath Poems 1979-1997. 1998)

O God, Creator of heaven and earth: Grant that, as the
crucified body of your dear Son was laid in the tomb and
rested on this holy Sabbath, so we may await with him the
coming of the third day, and rise with him to newness of
life; who now lives and reigns with you and the Holy Spirit,
one God, for ever and ever. Amen.

These are the readings for Holy Saturday service.
