I can't answer every question or objection

The other day, I saw a comment somebody left on a YouTube channel saying that he went from being a Christian to an atheist because of the failure of Christians to answer all his questions. I suspect a lot of Christians saw that and thought, "We need to do a better job of educating ourselves so we can answer people's questions so this doesn't happen." I think it's great and all that being able to answer everybody's questions is the goal, but realistically, I don't think it's a goal that can ever be met or that we should even expect that it should ever be met.

After all, no matter what worldview you subscribe to, there are going to be questions you can't answer about that worldview. If anybody claims to have all the answers, we ought to be suspicious because it seems more likely that they're making stuff up than that they actually have all the answers.

I don't know specifically what questions this person had that didn't get answered, but I think when it comes to adopting a worldview, there are two things we ought to consider without having to answer every single question or every possible objection somebody might raise to that worldview. One thing is that given all the information we have, which worldview is the best fit? Which worldview has the least problems and explains the most information?

The second thing you should look at is the core essentials of that worldview. There are some aspects to a worldview that are more important than others, and you want to focus on the most important stuff. The fact that adopting a worldview raises all kinds of questions isn't a big problem for that worldview unless those questions raise serious doubt about the essential elements of that worldview.

I think that as an honest defender of any point of view, you ought to be comfortable saying you don't know when you don't know. What I like to do when somebody asks me a difficult question is first let the other person know that I'm not sure, but then to offer whatever thoughts I have on the subject. If you try to offer your speculations before letting the other person know that they are speculations, it's just going to come across as dishonest.

One more point I want to make is that not all questions amount to objections. Whenever you find out something new, it almost always raises new questions. But the mere existence of an unanswered question doesn't amount to an objection. Not knowing how something happens or why it happens is not enough to argue that it doesn't happen. Our lack of knowledge doesn't, by itself, imply that there's nothing to be known. Our ignorance doesn't imply that there's no answer to be found. Questions can amount to objections, but you need a little more than ignorance to make those objections go through.
