The body of Christ should pray for the Texas coast as Hurricane Harvey makes landfall. Some people believe devastating storms are not sent from God and others believe they are. I believe it could be either. Scripture shows us that when God was getting the attention of Elijah, there were various examples of the power of nature forces.
He said, “Go out, and stand on the mountain before Yahweh.” Behold, Yahweh passed by, and a great and strong wind tore the mountains, and broke in pieces the rocks before Yahweh; but Yahweh was not in the wind. After the wind there was an earthquake; but Yahweh was not in the earthquake. After the earthquake a fire passed; but Yahweh was not in the fire. After the fire, there was a still small voice. When Elijah heard it, he wrapped his face in his mantle, went out, and stood in the entrance of the cave. Behold, a voice came to him, and said, “What are you doing here, Elijah?” - 1Kings 19:11-13
This would be an example of why God doesn't send natural disasters. But, to be more specific, these verses apply to Elijah the prophet of God. He was highly esteemed of God. Judgment was not for Elijah. I believe God was simply helping Elijah to not be afraid of this world and all its wicked threats.
Scripture also supports the explanation of natural disasters as being the judgment of God. If you don't believe that, just read the Book of Revelation. Granted, we would have to know for sure that judgment has come, because it's widely agreed that we live in the dispensation of Grace. However, it's also clear that we're approaching the end of the age. We just had a Solar Eclipse, which has often been seen as a sign of possible judgment. Is it a coincidence that the hurricane of all hurricanes is about to hit America during the 40 days between a Solar Eclipse and the Day of Atonement?
