Charles Spurgeon writes

There is no greater mercy that I know of on earth than good health except it be sickness; and that has often been a greater mercy to me than health.

It is a good thing to be without a trouble; but it is a better thing to have a trouble, and know how to get grace enough to bear it.

I am not so much afraid of the devil when he roars, as I am when he pretends to go to sleep. I think that, oftentimes, a roaring devil keeps us awake; and the troubles of this life stir us up to go to God in prayer, and that which looks to us ill turns to our good.

“We know that all things work together for good to them that love God, to them who are called according to his purpose.”
