I've been using The Divine Hours by Phyllis Tickle to pray the morning office. (I haven't managed to add noon prayer and vespers, but that's a different post.)
Anyway, this is the prayer appointed for this week, and I've been finding it very meaningful. I'll post it without further comment.
Most loving Father, whose will it is for us to give thanks for all things, to fear nothing but the loss of you, and to cast all our care on you who cares for us: Preserve me from faithless fears and worldly anxieties, that no clouds of this mortal life may hide from me the light of that love which is immortal, and which you have manifested to us in your Son Jesus Christ our Lord; who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.
