American evangelist Franklin Graham is not afraid to speak his mind and face criticisms left and right if he knows that the truth needs to be told for the betterment of his country. In light of last Friday's deadly terror attacks in Paris, Graham is renewing his call for authorities to tighten immigration policies in America.

"I've said this before, and many people criticised me for saying it. We must reform our immigration policies in the United States," he writes on his Facebook page. "We cannot allow Muslim immigrants to come across our borders unchecked while we are fighting this war on terror. If we continue to allow Muslim immigration, we'll see much more of what happened in Paris — it's on our doorstep."

Graham says France and the rest of Europe are already being overrun by young Muslim men from the Middle East, and they do not even know their backgrounds or their motives and intentions.

"Islam is not a peaceful religion as George W. Bush told us and as President Barack Obama has said — that is just not true," he stresses. "Our president and our politicians in Washington need to wake up before it's too late. This is not the time to be politically correct. Our nation's security is at stake."

Graham also believes that the future of America's children and grandchildren is at stake. The authorities need to take a bold stand against "any political or religious group who want to destroy us and our way of life to immigrate to this country."

The son of Billy Graham says his heart is extremely heavy knowing that at least 129 lives have been lost while 352 people are injured because of the terror attacks on Friday night "all because of hearts filled with hate and evil."

"There is only one who can change the human heart and that is God," he says. "The good news for our world is that God can change any heart willing to turn to Him in true repentance and faith in His Son Jesus Christ. Prayers do make a real difference — so let's continue to let the people of France know that we support them and are praying for them during these difficult days."
