" If I shut up the heavens so that there is no rain, or if I command the locust to devour the land, or if I send pestilence among My people, and My people who are called by My name humble themselves and pray and seek My face and turn from their wicked ways, then I will hear from heaven, will forgive their sin and will heal their land. "
- II Chronicles 7:13-14 NASB
