When tragedy strikes, Christians are often left asking, "Where was God? Why would He allow something like this?"
They really should have figured that out beforehand.
That sounds cold, I know, but right in the midst of personal tragedy is no time to be trying to figure out God's sovereignty over suffering and evil. We need to figure that out well ahead of time, so that, when trials do come (and they certainly will), we won't be tempted to doubt God's goodness.
For the rest of us—those of us who do have settled convictions on the doctrine of providence and the relationship between God's secret and revealed wills—we have to remember that we have not been called to lecture those who weep. We've been called to weep with those who weep (Romans 12:15).
Yes, our suffering brothers and sisters should have gotten their theological ducks in a row beforehand. There will be time for that later. Right after a great loss or during a difficult trial, they don't need your lecture. They need your sympathy.
