Thanks for asking. And thanks for expressing your personal discomfort or distress about the "destruction, pain, and suffering" described in news reports coming out of Haiti. Every child of God shares this same kind of discomfort since compassion is a trait believers are quick to express.

You ask how we may testify to others regarding God and his role in such disasters that have marked so much of human history since the fall into sin and will continue to do so (see Matthew 24:7,8). When we are tempted to question divine wisdom or love, our starting point is God's saving work for us sinners through Jesus Christ. Then we will appreciate him as our loving Father in heaven and will be content with what he chooses for us in our lives and what he chooses at a given time for the lives and deaths of others. We will also see disasters as opportunities
to show compassion and kindness to those who suffer.

We properly acknowledge that God is the primary agent of all things as Isaiah 45:7 says: "I form the light and create darkness, I bring prosperity and create disaster; I, the LORD, do all these things." God was not surprised by this earthquake or any of the five other earthquakes that took place in the world that same week.

But why did they happen? It is impossible to answer this question fully or authoritatively because God has not revealed all the answers to our "Why?" questions. " 'For my thoughts are not your thoughts, neither are your ways my ways,' declares the LORD" (Isaiah 55:8). Yet he reveals many reasons for allowing painful things to be a part of our lives. He may test our faith, force us to turn to his promises for strength, keep us humble when we become arrogant, and challenge us to grow to a wiser perspective. But no one explanation fits all of God's wise works in our lives.

God does these things also with unbelievers in mind. God's love for his creatures and his anger against sin are factors in all of God's doings as well, but we are insufficient to sort all of this out in a given event. We simply confess that an event like the earthquake in Haiti expresses God's wisdom, love, and anger blended in a way that is beyond our full understanding.
