Anne Graham-Lotz, the daughter of legendary Christian televangelist Billy Graham, recently wrote a letter to The 700 Club's longtime host Pat Robertson warning Christians that the day of "judgment is coming."

"One of the things He [God] has impressed on me is that we are living at the end of human history as we know it," wrote Graham-Lotz to Robertson in a letter last month. "In obedience, I am blowing the trumpet...sounding the alarm...issuing a national prayer initiative entitled '777: An Urgent Call to Prayer.'"

Graham-Lotz further explains how Christians can get a better relationship with God through fasting and prayer.

"The Call is for God's people to pray for each of the first seven days in the seventh month - July 1-7. Then on the 7th day, July 7, we are to pray and fast for 7 hours. The purpose is..." wrote Graham-Lotz.

"1. For God the Father to restrain, protect, and deliver His people from the evil that has come into our world. 2. For God the Son to be exalted, magnified, and glorified in His church, in our nation, and in our lives. 3. For God the Holy Spirit to fall on us in a fresh way, compelling the church to repent of sin and our nation to return to faith in the living God, resulting in a great national spiritual awakening."

The 66-year-old evangelist also revealed what people can expect this week when they visit her inspirational website.

"I will provide a prayer I have written for each of the seven days to help unite us in one spirit and one voice as we cry out to God. Please be assured there is no other agenda in this initiative. This is not about promoting anything or anyone. This is all about calling God's people together to pray, before it's too late, and judgment falls on our nation," wrote Graham-Lotz.
