A lot of people seem to think that you can't thank God in an acknowledgment, but I don't see why not. If you want to thank God for something, why not put it in your acknowledgment? I don't think there's any rule that says you can't do that.
Now, some people might say that it's not appropriate to thank God in an acknowledgment because it's supposed to be a list of people who have helped you with your work. But I think that if you want to thank God, you should go ahead and do it. I don't think there's anything wrong with it.
So, if you want to thank God in your acknowledgment, go ahead and do it. I don't think there's anything wrong with it.
