Franklin Graham, the son of renowned evangelist Rev. Billy Graham, suggested that God might strike the White House with lightning for celebrating the U.S. Supreme Court’s ruling on same-sex marriage with rainbow lightning last month. Graham wrote in a Facebook post on Tuesday that President Barack Obama might want to install “extra lightning rods” on the roof of the people’s house.

“Just three years ago, the president was on record as holding to the biblical definition of marriage. Now he can’t say enough about his support for the LGBT agenda – and right after the Supreme Court’s decision to legalize same-sex marriage, he had the gall to disgrace the White House by lighting it up with the gay pride rainbow colors to celebrate,” wrote Graham.

“This is arrogantly flaunting sinful behavior in the face of Almighty God. My advice? He might want to have some extra lightning rods installed on the roof of the White House,” he asserted. Graham first spoke out against the colorful White House display last week and informed his Facebook followers on the origins of the rainbow.

“This is outrageous – a real slap in the face to the millions of Americans who do not support same-sex marriage and whose voice is being ignored. God is the one who gave the rainbow and it was associated with His judgment. God sent a flood to wipe out the entire world because mankind had become so wicked and violent. One man, Noah, was found righteous and escaped God’s judgment with his family,” wrote Graham on his Facebook page last Monday.

Graham went on to explain that God used the rainbow as a sign to Noah that he would never use a flood again to “judge the world.” He also warned about God’s judgment. “Only those who are found righteous will be able to escape his judgment,” said Graham. The White House’s Twitter account used a picture with the rainbow lighting for an avatar following the U.S. Supreme court ruling and declared the legalization of same-sex marriage a “victory for America” days after the ruling.
