All rights reserved. God sends rain on the just and the unjust. I have often heard this verse quoted. It is almost always quoted out of context and completely misinterpreted.
Rain is interpreted as troubles and trials.
This verse is often used to explain why good people have to face trials. Maybe people think of rain as bad because it interferes with our camping and picnics. But these words were spoken to mostly farmers living in a land with low rainfall. They depended on rain for their survival. To them, rain was a picture of God's blessing.
