All Saints Day Prayer
(inspired by Luke 6:20-31)
Faithful God, source of every blessing:
teach us to love our enemies,
to bless those who curse us,
to pray for those who persecute us,
to turn the other cheek,
to share our possessions,
to give to those who are in need,
and to do to others
as we would have them do to us,
so that we may join that company of blessed saints
who feast with you in heaven;
through Jesus Christ our Lord.
