Dr. Craig, we always love to put you in the hot seat and we're going to do it again today.

We've got some good questions we received from listeners and viewers.

Question and answer, this question says Dr. Craig.

The following are two time-related questions that I've had on my mind recently.

One is the nature of time necessarily immutable or could the nature of time change in some fundamental way at the return of Christ?

And then number two, if you're interested in possibly sharing,

did your 13 years of studying God's relation to time influence your personal and or professional time management practices?

Well, in response to the first question, the nature of anything is immutable.

If something changes in its nature, then it undergoes an essential change and so ceases to exist.

So his first question is, could the time that we live in an experience be replaced by a different sort of time in the new heavens and the new earth after the return of Christ?

And I do think that's certainly possible. We may have no idea of what time would be like in the new heavens and the new earth, but I see no reason at all to think that it couldn't be different in some way.

Now, as for the second very practical question, I have to say no, my study of divine eternity and time didn't do anything to influence my time management practices other than demand that I be extremely efficient in my study and writing, so it's to get through this monumental research project.

I think that the philosophical term for that time management system bill is Jan, at least to a big extent, and we all know that.

Question number two, Dr. Craig, in the first philosophical argument for the second premise of the column, the proofs, defenses, we try to invalidate the existence of an actual infinite by illustrating different situations in which absurdities result.

One example is Hilbert's hotel, where we are shown that you cannot have an infinite number of rooms due to contradictions that result from different operations.

Why does this prove that there can be no actually infinite qualities in any situation rather than only prove that rooms in a hotel are the sort of things that cannot be of an actually infinite quantity?

Objects can be removed, standing in contradiction to Cantorian set theory, so it makes sense that they cannot be actually infinite, but we cannot remove or divide time items in the set of past events.

So it seems to be a different kind of thing. How can we translate the findings of a thought experiment applying to objects to time?

I think that the reason that the conclusion could be generalized is because there's nothing about the illustration of a hotel that is peculiar to the argument, and indeed I provide numerous different illustrations that are arbitrarily chosen to show the absurdity of an actually infinite number of things.

So these are not limited simply to rooms in a hotel. With regard to the series of past events, we can imagine, for example, taking mentally every other event into the past, and comparing that with all of the events in the past, and asking which one is the greater series, and it turns out that they're exactly the same.

And that's the same situation that you have with Hilbert's hotel and moving guests around with regard to events in the past. You just do it as a thought experiment.

Question number three. Hello, Dr. Craig. If I'm not mistaken, you have stated before that salvation is not combined to a specific denomination of Christianity.
