Let’s suppose, for the sake of argument, that Pat Robertson (a) is correct in his history of the people of Haiti, and (b) he has some evidence that it happened. Even if those are both true, this is not the time to say something that people will view as laying blame on the innocent. Despite his statement at the end that he hopes and prays that the people of that island would turn to God and that he prays for their immediate relief, people don’t see it as a statement for mercy. They see it as a statement of blame, which it is.
So let’s speculate for a bit. The better time to say that would have been six months ago. The same thing would have happened, everyone would have called him a kook and dismissed him, but when the earthquake struck, somebody might have remembered what he had said and perhaps then it would have been received with a soft heart.
This is the same type of thing he said after 9-11, which he blamed on America’s sinfulness. It may have been true, but it was not received because of the events at the time.
Compare and contrast with Billy Graham’s outfit, which is just soliciting donations and speeding relief. They will likely see many many more donations than CBN, and will be more effective in their ministry.
When spreading the gospel, one must always be sensitive to the weaknesses and tendernesses of others, lest you unwittingly harden the ground you are trying to sow.
