Throughout most of Spurgeon’s ministry, both he and his wife suffered greatly with ill health. But rather than remonstrate bitterly with God, he recognized trials as a necessary part of his sanctification, and as a part of fitting him for ministry. As Iain Murray writes, Spurgeon believed that without without difficulties,

he would have been ruined. Fallen men, though Christians, cannot long be surrounded by popularity and success without the special help of God. ‘Our God takes care always to have the security that, if He works a great work by us, we shall not appropriate the glory of it to ourselves. He brings us down lower and lower in our own esteem . . . Some trumpets are so stuffed with self that God cannot blow through them.’ ‘You may rest quite certain that, if God honors any man in public, he takes him aside privately, and flogs him well, otherwise he would get elevated and proud, and God will not have that.’ ‘Many a man has been elevated until his brain has grown dizzy, and he has fallen to his destruction. He who is to be made to stand securely in a high place has need to be put through sharp affliction. More men are destroyed by prosperity and success than by affliction and apparent failure.’
