Welcome to our new series, 'Let us Pray', in which we ask well-known personalities to share their favourite passage of scripture or prayer. We will hear from Christians, Muslims, Rastafarians and persons from all religious beliefs and denominations, and this week we turn the spotlight on the controversial Deputy Commissioner of Police Mark Shields.

"As a child, whenever my father put me to bed he would say this prayer from the Book of Common Prayer, titled 'A Collect for Aid against Perils'.

"Lighten our darkness, we beseech thee, O Lord; and by thy great mercy defend us from all perils and dangers of this night; for the love of thy only Son, our Saviour Jesus Christ. Amen."

Shields said that although this prayer refers to the night, he often thinks of it as a prayer to seek protection from all the perils and dangers that he encounters in his job as a police officer.
