It's found in 2 Chronicles 7:14:
"If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."
If ever a land needed healing, it is this one. Remember, God plus one is a majority in any situation. Reformation and Revival are both needed. Read your Bible and work like it all depends on you, and then pray like it all depends on God. And remember too that He is always in control.
