Popular evangelist Billy Graham's daughter Anne Graham Lotz has offered a grim warning for the future, saying that God's judgment is coming to America and "it's going to be ugly."

She recalled the time when she and Joel Rosenberg taught through the book of Joel as they led the prophecy seminar at The Billy Graham Training Center at The Cove. She delivered the first two messages, which covered Joel 1:1 and Joel 2:17, and the impact the messages had on her was so profound.

"Both times, when I stepped off of the platform, I knew God had spoken. The messages almost made the hair stand up on the back of my neck. Why? Because God was clearly warning that His judgment is coming on America and on our world, and it's going to be ugly. I knew it then, and I know it now," she wrote on her website.

Anne said that Jesus is going to return soon to take all of His followers to heaven. And while this means deliverance for His people, she questioned the impact it will have on the world when every Christian disappears from the face of the earth.

"Institutions will collapse. Banks will close. The Stock Market will plunge. Planes will fall out of the sky. Cars will crash on the road. Government in America at every level will disintegrate. Families will be torn apart. In the unprecedented turmoil, our nation will be vulnerable for our enemies to seize the moment and attack us. There will be mass chaos, confusion, fear, grief, despair, anger, threats, danger... judgment," she said.

Because of this, Anne initiated the MAYDAY Prayer Initiative, where Christians would pray and fast from May 15 to 23 for "an outpouring of the Holy Spirit."

These will be the nine days between the day of the Ascension of Jesus and the Day of Pentecost, said Anne, and they hope to pray for the nation to return to faith in the living God and for Him to delay and soften the judgment that is coming to the world.
