According to a priest who worked with Mother Teresa for years, her favourite prayer, and one she recited every day of her life, is one written by the great English churchman John Henry Newman. In it, it he speaks of that glimmer, that radiance that reveals the destination, the reason for the journey (Thanks to Marjorie Dannenfelser of Susan B. Anthony List for details:
Help us to spread your fragrance everywhere we go.
Flood our souls with your spirit and life.
Penetrate and possess our whole being so utterly,
that our lives may only be a radiance of yours.
Shine through us,
and be so in us,
that every soul we come in contract with
may feel your presence in our soul.
Let them look up and see no longer us,
but only Jesus!
Stay with us,
and then we shall begin to shine as you shine;
so to shine as to be a light to others;
the light O Jesus, will be all from you,
none of it will be ours;
it will be you, shining on others through us.
Let us thus praise you in the way you love best,
by shining on those around us.
Let us preach you without preaching,
not by words but by example,
by the catching force,
the sympathetic influence of what we do,
the evident fullness of the love our hearts bear to you.
