At each service daily, a prayer, or 'collect' is used from the Book of Common Prayer. The collect for this week, the Second Sunday before Lent is:
O LORD God, who seest that we put not our trust in any thing that we do; Mercifully grant that by thy power we may be defended against all adversity; through Jesus Christ our Lord. Amen.
