Here is an informative link I found on the DailyMail:
The photographs and reports tell a really horrendous story. I don’t know how to respond. I’m very moved by it. In my heart of hearts I ask God why. Many others ask the same; in fact, in times like this God has his character impugned and insulted quite alot. But there are a few things that must be said:
1) In asking why God can let this happen, we cannot fully understand the ins and outs of why. God has the right and authority to make the decisions he thinks are the best and he knows infinately better (and more) than we do.
2) In the midst of tremendous suffering a tremendous good can come whose value far outweighs the pain. Suffering can bring us to a definitive point in our lives with eternal consequences. If through pain one decides to cast their hope in God and be eternally saved from it, then the temporary suffering is well-worth it, as many Christ-followers I know will tell you from personal experience. It also develops your character. The hotter the iron is fired, the stronger and better quality it is.
3) Lest we think that we are some experiment which God is detached from, know that God knows exactly what it is like to suffer like these people in Haiti are suffering — because he was a human Himself. Jesus was God incarnate in human flesh; he experienced the pain of loss of loved ones, being without a home, of physical wounds and death. He knows the tears those Haitian mothers are shedding, because he shed them himself. And he did it voluntarily, for her sake, so that she can be eternally redeemed from her sins.
Knowing the value pain can bring into human lives, and knowing God experiences it with us, our questions cannot become accusations. But God offers everyone a chance to both live victoriously in a world of suffering and to enter a world without suffering for eternity — acquired by trusting in Christ for your eternal destiny.
Jesus once comforted his friend Martha, a woman grieving over the death of her brother, with these words, which are appropriate to quote here: “Jesus said to her, ‘I am the resurrection and the life. The one who believes in me, even though he dies, he shall live. Whoever lives and believes in me will never die.” – John 11:25
