Miracles

At Confirmation on Monday night, we talked a lot about miracles. Do they still happen? When we look into a coincidence, are God's fingerprints everywhere?

Today, we see another list of ages:
700
438
433
437
239
239
230
148
205

Another thing I noticed is that most people are having babies at 30, not 65. Now that the earth is re-populated, is God preparing us for a shortened lifespan or is he getting us ready for Sarah's miracle in which the young couple is pushing triple digits?

Does God want us to know that Isaac is around and the promise continues solely due to him?
