Being from someone who is "now a Christian," that article neither mentions Jesus by name or says anything about his teachings, apart from a brief mention of "religion as something separate from politics."
If Ayaan Hirsi Ali has abandoned atheism, that's a step in the right direction.
She's now attending church, which is also a step in the right direction. Hopefully it's a church where she will hear the Gospel, and consequently trust Jesus for the forgiveness of her sins.
I don't (yet) see a person who has become a Christian. I see her as someone who has recognized the intellectual bankruptcy of first Islam and then atheism, and has latched on to the ethical teachings of Christianity.
As I always say about high-profile conversions ... wait and see.
