Primate of Nigeria

I am writing to let you know how deeply your Christian brothers and sisters here in the UK feel for you all in the midst of the violence and uncertainty that has overtaken you in Nigeria and especially in Abuja in recent weeks.  In the face of mindless and brutal aggression, you have been asked to witness to the essential Christian truths, and we honour your courage and faithfulness.  'You have kept my word and have not denied my name' (Rev.3.8).

Be sure of many prayers for you and your people as you seek to build again a peaceful and secure environment for all.
