Prayer for Lent

I missed this last week. The prayer for the third week of Lent in the BCP is powerful:

Almighty God, you know that we have no power in ourselves to help ourselves: Keep us both outwardly in our bodies and inwardly in our souls, that we may be defended from all adversities which may happen to the body, and from all evil thoughts which may assault and hurt the soul; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
