As the day draws closer for America to officially accept the Iranian deal, God' Word is forever sealed in Heaven:

“I will show wonders in the heavens and in the earth: blood and fire and pillars of smoke.
The sun shall be turned into darkness, and the moon into blood, 
Before the coming of the great and awesome day of the Lord. 
And it shall come to pass that whoever calls on the name of the Lord shall be saved. 
For in Mount Zion and in Jerusalem there shall be deliverance, 
As the Lord has said, among the remnant whom the Lord calls." Joel 2
