I finished this book two days ago with tears in my eyes. I wish I'd read it a long time ago.
Divided into three parts (Understanding the Furnace, Facing the Furnace, Walking Through the Furnace), Keller's book begins with a philosophical and historical treatment of suffering as other world religions and philosophies have endeavored to explain it. Not surprisingly, they all fall short and leave much to be desired. But the biblical understanding of and encouragement through suffering holds up! What I loved about this book is that Tim Keller doesn't shy away from the big questions: Why do we suffer? What's the purpose? If God is good, why does He let us suffer? How do we get through it? In true Keller fashion, he answers the questions and takes you to Scripture.
While some readers may want to skip the first section because of the exploration of the world's handling of suffering through history (and indeed, Keller encourages readers to feel free to do so), I felt that section laid necessary groundwork for the rest of the book. Readers will find the last section to be especially helpful if they are currently walking through a trial or season of grief. The chapter on the story of Job is worth the price of the entire book, in my opinion. I underlined so much in this book, but I'll share a few quotes below to give you a flavor of it.
“Jesus was patient under even greater suffering for us, so we can be patient under lesser suffering for him. And heaven will make amends for everything.” (p. 13)
“It is the most liberating idea possible and it ultimately enables you to face all suffering, knowing that because of the cross, God is absolutely for you and that because of the resurrection, everything will be all right in the end.” (p. 49)
“Suffering dispels the illusion that we have the strength and competence to rule our own lives and save ourselves.” (p. 49)
“If you seek God as the nonnegotiable good of your life, you will get happiness thrown in. If, however, you aim mainly at personal happiness, you will get neither.” (p. 187)
“A Christian man who develops lymphoma should not think he is being punished for a sin, though he must not, on the other hand, miss this opportunity to put his roots down into God and discover a dimension of spiritual growth and wisdom he would never otherwise have had access to.” (p. 208)
“When you suffer without relief, when you feel absolutely alone you can know that, because [Jesus] bore your sin, he will be with you. You can know you are walking the same path Jesus walked, so you are not alone—and that path is only taking you to him.” (p.293)
“You will never really understand your heart when things are going well. It is only when things go badly that you can see it truly. And that's because it is only when suffering comes that you realize who is the true God and what are the false gods of your lives. Only the true God can go with you through that furnace and out to the other side. The other gods will abandon you in the furnace.” (p. 308)
“On the cross, Jesus got what we deserve, including this cosmic, profound pain and restlessness. He got what we deserve, 2 Corinthians 5:21 says, so we can get what he deserves.” (p.311)
