Spurgeon

"Though we were washed in a sea of fire, we should not lose an atom of our sin by suffering. Nay, the very flames of hell shall never purify a soul, or purge away a single sin; he that is filthy shall even there be filthy still. There is nothing in suffering, any more than there is in joy, in and of itself, to make a man holy. That is the work of God, and of God alone; yet God overrules both our joy and our grief to accomplish his own divine purpose by his Spirit. It is God who sends the wind; so, once again, I want you to pause, and bow your heads before him who sends all your trouble. Do not be angry with God for what he does to you; but feel that it must be right even though it should tear everything away from you, though it should leave you a widow and houseless, though it should strip you, and though it should even slay you. God is God still; and the deeper your trouble, the greater are your possibilities of adoration; for, when you are brought to the very lowest, it is that, in extremis, you can raise the song in excelsis, out of the deepest depths you can praise the Lord to the very highest. When we glorify God out of the fires of fiercest tribulation, there is probably more true adoration of him in that melody than in the loftiest songs of cherubim and seraphim when they enjoy God, and sing out his praises in his presence above."
