i came across this blessing in gerard kelly's book church actually and was pleased to discover it is online on his spoken worship site here. i used it last night at an evening marling a moment of someone journeying on to something new. gerard's words are always wonderfully crafted... i am making it a worship trick (23 in series 4) seeing as i haven't added any for ages now!
May God, in whose furnace faith is forged; in whose being beauty breathes; at whose dawning darkness flees, shine on you.
May the Father, whose love for you beats with a rhythm time itself can’t stop; whose presence in your exile is the promise of home; whose certainties are deeper than the cellars of your city; whose breath is life, breathe on you.
May the son, whose story is a mirror of your own; who has journeyed into darkness to find a key to your prison; who has dived the deepest oceans to find pearls for your wisdom; who has looked into your heart and found a beauty worth the battle; who has written your name on a white stone carved in secret, hold you.
May the Spirit, who has waited millennia to fill you; who shaped the word that moved the wind of the morning that conceived you; who holds the earth on which you stand as an artist holds a candle; who fully knows you, wholly own you
So may God the faithful father, God the scarred son, God the sculpting spirit journey with you
[update: i also saw this blessing for leaders which i have used before had been put online by tom brackett]
