We’re using the book “Handbook of Apologetics” by Peter Kreeft and Ronald Tacelli to go over the arguments for the existence of God. Dr. Kreeft teaches logic in two major universities, so his arguments tend to be clear, concise and very helpful.
Last week we looked at the Kalam Cosmological Argument, and this week we’ll answer some questions regarding it:
Question 1:
Christians believe they are going to live forever with God. So they believe the future will be endless. How come the past cannot also be endless?
Reply: The question really answers itself. Christians believe that their life with God will never end. That means it will never form an actually completed infinite series. In more technical language: an endless future is potentially—but never actually—infinite. This means that although the future will never cease to expand and increase, still its actual extent will always be finite. But that can only be true if all of created reality had a beginning.
