John Piper has a series of biographical presentations on noteworthy Christians called "Men of Whom the World was Not Worthy"
Rosemary and I have been very blessed and encouraged listening to these presentations, and I would heartily recommend them.
You can find them here and here:
We were particularly touched by the story of Adoniram Judson, missionary to Burma. He was the first American missionary to leave North America, and he served almost 40 years in Burma and left a significant mark on the nation.
At the same time, his life was marked by great difficulty.
He had 3 wives, who all died. Except for one son, all of his children died - most as infants, one as a toddler.
What he wrote about how he made it through such difficulty is powerful:
"If I had not felt certain that every additional trial was ordered by infinite love and mercy, I could not have survived my accumulated sufferings."
These were the words of Ann, his second wife, after her second child, the toddler, died:
"Our hearts were bound up with this child. We felt that he was our earthly all, our only source of innocent recreation in this heathen land. But God saw it was necessary to remind us of our error and to strip us of our only little awe. Oh may it not be in vain that he has done it; may we so improve it that he may stay his hand and say, 'it is enough'."
I am impressed and encouraged by faith like that - faith that does not get angry at God in the face of difficulty, but trusts in His knowledge and love even when it doesn't have answers to the question of 'why?'.
