My God, my Sustainer,
I know I will not love you as much as you deserve,
But only insofar as you enable me to love.
This will surely not amount to all the love I should show,
But it will amount to all the love I can show
Because it is impossible to love you
Beyond the power to love that I possess.
I will love you more
If you will make me able
Howbeit that this never will amount
To as much as you are worthy to be loved.
~ St Bernard of Clairvaux, my translation from French.
