From a newly discovered letter from William Wilberforce to a 14 year old girl:
.... A Traveller on an open Common in such a Storm of Hail & Rain as we had this Morning would find his spirits cheered by seeing on the distant horizon, the Cloud clear'd away and the Sky looking sunny and cheerful. So you, I doubt not, can view the Sunshine gilding Your future prospect. And yours my dear Girl is a Sun which will never go down, but will get brighter & brighter with a Warmth & brilliance, of which now you can have no conception. I dare say you know & like Cowper. He, you know, speaks of "a Vault unsullied with a Cloud." Now therefore accustom yourself to think "the Scene around me is gloomy and darksome, but a friendly and, that a divine Hand of a kind and loving Saviour, is leading me on the Way He sees best for me, & in His own good time He will bring me into the Light.The post at Quaerentia explains how the letter was found and explains why Wilberforce would emphasize such matters when writing to a young girl.
As I know He is Truth itself, he cannot deceive me & He has promised to be a Shepherd full of kindness as well as Care to the Lambs of His flock. He would not let me suffer pain if He were not persuaded it would be for my benefit and I will therefore receive all and submit to it all He orders for me, as that which is sure to be more than made up to me. So that if more I have to bear now, the more I shall have to rejoice hereafter. ....
