After doing further research, I'm still not sure about Yousef's sincerity. At this point, IMHO, the jury is still out, and I will leave it up to you to make up your own mind. I cannot say with certainty that I have been deceived and beguiled; therefore, I can't say that I misled you.
Walid Shoebat, a former radical Muslim and member of the PLO, converted to Christianity in 1994, and questions the sincerity of Mosab Hassan Yousef. You can visit his website and view a video interview with Mosab Hasan Yousef on Arab television where he seems to display Palestinian sympathies.
However, in a more recent speech given before Jewish Congress in Frankfurt, Germany on Oct. 23, 2011, Mosab Hasan Yousef says that he doesn't just like Israel, he loves Israel. That's a tough statement for someone who is alleged to still be a supporter of Hamas since Hamas doesn't believe that Israel should even exist as a nation state. Here is his message in its entirety.
My thoughts on Mosab Hasan Yousef at this point in time: I believe he is a Christian, a young believer who needs our prayers daily. He is under tremendous pressure, and even as I write this, the Obama administration is seeking to deport Yousef back to Israel. If you haven't yet done so, read Son of Hamas and decide for yourself, then pray for Mosab Hasan Yousef. Pray for him to grow in his faith as a one of Yeshua's disciples.
