Domain Query: The Age of Apostasy

Time for another Domain Query - this time I answer a very interesting question from reader "H" about whether or not there is any hope for apostates. Here is the original question:

Forgive me if this is an annoying question you would rather not answer - I understand if that is the case. If you’re inclined to answer, I wanted to ask what your thoughts are about apostasy and returning to the faith. I was a Christian 10 years ago and said that I no longer believed after believing atheist arguments I read about online. Now, I see that many of those arguments are unsound and I feel like our overly hedonistic culture is empty and I’ve been lied to. I’ve wondered if I can return to Christianity and if God would accept me back... but there is the verse in Hebrews that suggests otherwise and I feel I may be damned and there is no hope. 
Perhaps you can’t answer whether or not an apostate can return. I wanted to ask a Christian who really seems to follow the Bible, as I have read Christian websites saying that verse in Hebrews is misinterpreted. As you point out on your blog, though, many modern churches and Christians are unbiblical and twist or ignore scripture. I don’t want to lie to myself, and I must accept the consequences of my choices. But do you think an apostate can return to God, or is that not possible? 

I answered this at some length in writing, and decided to address the same issue in spoken form here.
