When I shut up heaven and there is no rain, or command the locusts to devour the land, or send pestilence among My people,
if My people who are called by My name
will humble themselves, and pray and seek My face, and turn from their wicked ways,
then I will hear from heaven, and will forgive their sin and heal their land. (
2 Chronicles 7:13-14 NKJV)
The boldened parts are mine emphasis added. This is how God has ordained the move of God to be.
