What a well-written, intelligent, and respectful rebuttal. Thank you.
I really wish the message of Jesus, exactly as you described it, was better understood by all of the anti-Christians. It's a seriously good message, yet so many people want to hate on it without giving it a chance.
As for the Old Testament, I'm continually blown away by how much of it foreshadows Jesus, His ministry, and His apostles. The number of times this happens is far too great for me to count, though I'm sure some biblical scholars have attempted to do so. Having grown up in the church, and clearly having read the good book, you may well be more familiar than I am with all of the foreshadowing, as I'm a convert who was raised atheist and didn't find God until my 30s. I still have a lot of catching up to do, and I'm sure I always will. But suffice it to say, there's foreshadowing through and through.
Before Christ, we made God's work more difficult. Humanity wasn't wholly ready to follow Him. Abraham and his descendants were, at least they were enough to form a series of binding covenants. But until we were ready to receive Christ, God did what needed to be done to lead His first non-begotten son to the point when Christ could successfully arrive. And that, I believe, explains why the OT played out the way it did.
As for twin roe deer, I have no doubt God appreciates the form of a woman. Otherwise He'd not have made her look as He did, and He'd not have predicated our entire civilization upon marital intimacy.
As for the scripture that we now consider canonical, do you really think God had no hand in the Church's selection? I find it implausible that He'd take the effort to inspire various works of scripture, but then leave their canonicalization unguided.
I grew up an atheist, surrounded by secular culture. While I haven't read either of those particular books, I've read so many other arguments against God over the years. Yes, my faith is strong, but no, I don't desire to subject myself to the temptation to deny God. I have no doubt the books offer thought-provoking and compelling arguments, as both of those authors are intelligent. And I have no doubt that some Christians have read them and offered critiques and rebuttals, as with any opinionated book. Also I have so many books that I've bought but haven't read yet, and I'm working through them slowly, but I keep buying more! I'm pretty frugal overall, but I definitely lack some self-control when it comes to buying books. So overall, no, I won't read those, but I honestly do appreciate your recommendations. Thank you.
