A prayer for this week

Almighty Father,
you have given your only Son
to die for our sins
and to rise again for our justification:
grant us so to put away
the leaven of malice and wickedness
that we may always serve you
in pureness of living and truth;
through the merits of your Son
Jesus Christ our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.
Amen.
