Samaritan's Purse chief Franklin Graham, the evangelist son of preaching legend Billy Graham, says eventually ISIS will bow to Jesus.
In a Facebook posting Tuesday, he followed up on Monday's warning that, "The storm is coming."

He was lamenting the fact that when ISIS released a video of the beheadings of 21 Egyptian Christians in Libya, Muslim leaders were silent.
"Can you imagine the outcry if 21 Muslims had been beheaded by Christians? Where is the universal condemnation by Muslim leaders around the world?" he wrote.

"We'd better take this warning seriously as these acts of terror will only spread throughout Europe and the United States. If this concerns you like it does me, share this," he said.
On Tuesday, he said, "The evil of ISIS really shouldn't shock us – it is fully in keeping with their ultimate agenda of hastening a final apocalypse."

That a "final battle" will come is confirmed in the Bible, he said, and it "will result in the defeat of Satan and all those allied with him."
He continued, "One thing is for sure – one day every knee will bow and every tongue will confess that Jesus Christ is Lord, to the glory of God the father."
His comments come amid controversy over the White House comment on the murders of the 21 Christians.
Obama's condemnation of the violence failed to mention the victims were captured because they were Christian, and they were killed because of their faith.

Instead, the president's statement called then "Egyptian citizens."
"This heinous act once again underscores the urgent need for a political resolution to the conflict in Libya, the continuation of which only benefits terrorist groups, including [ISIS]," the statement said.
Graham, who also heads the Billy Graham Evangelistic Association started by his father, has been making statements of late that don't align with politically correct thought.
On the issue of same-sex "marriage," he praised Alabama Supreme Court Chief Justice Roy Moore for resisting it.

"No earthly court has jurisdiction over the infallible Word of God," Franklin posted.
And when Obama attacked Christians in a speech at the National Prayer Breakfast, Graham schooled the president on the facts in history.
"Today at the National Prayer Breakfast, the president implied that what ISIS is doing is equivalent to what happened over 1,000 years ago during the Crusades and the Inquisition," he wrote at the time. "Mr. President – Many people in history have used the name of Jesus Christ to accomplish evil things for their own desires. But Jesus taught peace, love and forgiveness. He came to give His life for the sins of mankind, not to take life.
"Muhammad on the contrary was a warrior and killed many innocent people. True followers of Christ emulate Christ – true followers of Muhammad emulate Muhammad," Graham wrote.
Obama had said: "Unless we get on our high horse and think this is unique to some other place, remember that during the Crusades and the Inquisition, people committed terrible deeds in the name of Christ. And in our home country, slavery, and Jim Crow, all too often was justified in the name of Christ."
WND also reported when he said Obama simply doesn't understand Islam.
"In his speech, the president made this baffling comment about Islam: 'Islam teaches peace. Muslims all over the world aspire to live with dignity and a sense of justice. And when it comes to America and Islam, there is no us and them – there is only us, because millions of Muslim Americans are part of the fabric of our country,'" Graham wrote in a commentary for Decision magazine at that time.
But he said that doesn't line up with the facts.
Obama, he asserted, doesn't understand Islam.
"Even President Bush in the previous administration called Islam a peaceful religion. Both men have done a great disservice to the American public by not understanding Islam and its teaching in the Quran," Graham wrote.
He wrote: "Mr. President – followers of a peaceful religion do not cut off the heads of innocent people in barbaric fashion. … Mr. President – believers in a peaceful religion do not kidnap 300 young schoolgirls as Boko Haram did in northeastern Nigeria in April and reportedly [sell] them to men to be sex slaves. … Mr. President – men who practice a peaceful religion do not detonate bombs on an American street during a marathon race to kill and maim innocent people. … Mr. President – no one who belongs to a peaceful religion would even consider hijacking airlines and flying them into buildings occupied by thousands of innocent people beginning their workday. … Mr. President – no peaceful religion would tolerate, let alone practice, female circumcision, require a women to have her husband's permission to leave her home and take up employment, and restrict her ability to receive justice."
Meanwhile, Fox News and others reported Egypt's response to the killing of Christians in Libya was to dispatch warplanes to hit ISIS militants.
They killed as many as 64 militants and destroyed the terrorists' training camps and weapons supplies.
