Severe suffering seems unacceptable to us precisely because we are unaccustomed to it.
Susanna Wesley had nineteen children; nine of them died before they reached the age of two. Puritan Cotton Mather had fifteen children and outlived all but two. Ironically, the problem of evil and suffering seems worse to us who live in affluent cultures precisely because we face less of it than many people have throughout history.
I heard an exasperated woman at a restaurant table loudly proclaim that her Porsche had to be taken in for repairs and now she had to drive her Audi. In contrast I have met devout Christians in Africa and Southeast Asia who have endured famine, genocide, and persecution, yet smile genuinely as they affirm God’s goodness and grace.
C. S. Lewis wrote,
Imagine a set of people all living in the same building. Half of them think it is a hotel, the other half think it is a prison. Those who think it is a hotel might regard it as quite intolerable, and those who thought it was a prison might decide that it was really surprisingly comfortable. So that what seems the ugly doctrine is one that comforts and strengthens you in the end. The people who try to hold an optimistic view of this world would become pessimists: the people who hold a pretty stern view of it become optimistic. 
People who ask why God allowed their house to burn down likely never thanked God for not letting their house burn down the previous ten thousand days of their lives. Why does God get blame when it burns, but no credit when it doesn’t? Many pastors and church members have experienced church splits, feeling the agony of betrayal and disillusionment. But where were the prayers of gratitude back when the church was unified? Our suffering seems extreme in the present only because God has graciously minimized many of our past sufferings.

“Why doesn’t God smite this dictator dead?” is a question a little remote from us. Why, madam, did he not strike you dumb and imbecile before you uttered that baseless and unkind slander the day before yesterday? Or me, before I behaved with such a cruel lack of consideration to that well-meaning friend? And why sir, did he not cause your hand to rot off at the wrist before you signed your name to that dirty bit of financial trickery? You did not quite mean that? But why not? Your misdeeds and mine are none the less repellent because our opportunities for doing damage are less spectacular than those of some other people. Do you suggest that your doings and mine are too trivial for God to bother about? That cuts both ways; for in that case, it would make precious little difference to his creation if he wiped us both out tomorrow. 
Our birthright does not include pain-free living. Only those who understand that this world languishes under a curse will marvel at its beauties despite that curse. C. S. Lewis’s final article, published after his death, carried the title “We Have No Right to Happiness.” Believing that we do have such a right sets us up for bitterness.
Fallen beings could not survive in a perfectly just world where God punished evil immediately.
What if every time I gave a hundred dollars to feed the hungry, two hundred dollars appeared in my wallet? Or when I spoke a kind word to a weary supermarket checker, I received a Starbucks gift card?
Suppose that every time a man yelled at a child or looked at a woman lustfully, a painful shock jolted his frontal lobe? Or when he lied, he got an instant toothache or was struck dead by lightning?
If we think we want all evil judged now, we’re not thinking clearly.
Were such rewards and punishments built into our lives, the world would certainly be more just—but at what cost? We would base our obedience on instant payoffs or the avoidance of instant pain, not on loving God. Our behavior might improve, but our hearts wouldn’t. Faith would fade, because faith means trusting God to eventually make right what is now wrong.
Do you believe the world would be a better place if people immediately paid the just penalty for every sin? In God’s sight, every evil is a capital crime (see Romans 6:23). The woman who tells a “little white lie,” the teenager who shoplifts, the greedy man, the gossiper, all would instantly die. D. A. Carson writes, “Do you really want nothing but totally effective, instantaneous justice? Then go to hell.” 
God restrains suffering through our limited life spans—people don’t endure eons, millennia, or centuries of suffering, but only decades, years, months, weeks, days, and hours.
Take the total number of years you believe human life has existed. Now, ask yourself what portion of that time any one human being has suffered.
Suppose God permitted evil and suffering, yet limited them to one ghastly year of human history. Would we consider that duration of evil and suffering acceptable? What about one month? If someone could prove that we would become greater and happier beings for all eternity as a result, would you think it right for God to allow ten seconds of intense suffering? Likely you would.
Once we make that admission, do you see where it puts us? If we could justify ten seconds, then why not ten hours, ten days, or ten years? And in eternity, as we look back, how much longer will ninety years seem than ninety minutes?
Who holds the record for suffering among all human beings alive today? As I write, the oldest person in the world is 114 years old. She hasn’t suffered her whole life. But suppose she suffered significantly for a century. Most people, obviously, will endure much less. Some suffer severely for five days, weeks, months, or years; some, perhaps, for fifty years. However, no one in this world suffers for 10,000, 1,000, or even 130 years.
To say God takes too long to bring final judgment on evil and suffering imposes an artificial timetable on someone time cannot contain. God’s Son entered time in his incarnation. Though he understands our impatience, he won’t yield to it—and one day we’ll be grateful that he didn’t.
God allows substantial evil and suffering because he values our sense of neediness and trust as we turn to him for his grace.
Each year before Christmas we look forward to our church choir singing “Send the Messiah.” The haunting lyrics and powerful presentation resonate within us:
The cry of generations echoes in the heart of heaven....
I need a Savior who will walk the earth down here with me.... Send the Messiah, I need his love to own me. 
God sent the Messiah once, but he will send him again to deliver us. Paul, likely within months of his death, said God will grant a special eternal reward “to all who have longed for his appearing” (2 Timothy 4:8). What makes us long for our Lord? Isn’t much of it because of the evil and suffering we face in this life?
Thankfully, while the Messiah may not return to Earth as soon as we’d like, he promises, “Surely I am with you always, to the very end of the age” (Matthew 28:20). So while we long for and pray for God to send the Messiah to bring an end to this age of evil and suffering, we need not wait until then to enter his presence.
In light of the work done by Christ, our sympathetic high priest, we’re told, “Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need” (Hebrews 4:16).
Until God sends the Messiah to rescue this world, or he rescues us through our deaths, may we approach his throne confidently, seeking his fellowship, comfort, mercy, and grace in our time of need... today, this very hour.
