A Short Period of Time in this Finite Universe
Everybody on the earth and in this universe dies someday and none can live forever except the God.
The earliest stages of the universe's existence are estimated as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.However, this age of the universe might look so short, since we can easily imagine the number more than 13.8 billion.
(https://en.wikipedia.org/wiki/Chronology_of_the_universe)
For example, 13.8 billion seconds are equal to almost 160,000 days or about 440 years. And 440 years ago, it is about 1570 when the Philippines were conquered by Spain or the Battle of Lepanto took place where ”a fleet of the Holy League, a coalition of European Catholic states arranged by Pope Pius V, inflicted a major defeat on the fleet of the Ottoman Empire in the Gulf of Patras (https://en.wikipedia.org/wiki/Battle_of_Lepanto)."
It is also said that the earth was created 4.6 billion years ago. The time of life of the earth is about one third of that of the whole universe.
Or 13.8 billion years are equivalent to less than 4.4 x 10^17 (10 raised to the power of 17) seconds or 4.4 x 10^26 nano-seconds, while light travels 1 foot per nano-second.
In other words, this world has existed for less than 10^18 seconds while we can imagine the number of 10^180000 or more, while it is assumed that the God lives forever.
Our wisdom or intelligence is restricted by this time scale of 10^18 seconds while the God lives more than 10^180000000000000000000 seconds. Then, how much can we know about the God? Or how can we make our voices or prayers reach the God? If we lived 100 years and we prayed to the God all through our life, it would take just 3 X 10^9 seconds, which is just 0.00001% of the life time of universe.
So, physically or materially it is hard to expect that our voices or prayers would take the attention of the God.
However, according to the content of the teaching by Christ Jesus, the God surely listens to our prayers. It means that there is the spiritual space above this material universe that has existed for only countable number of years or seconds. The spiritual space and Heaven should exist forever. It should have existed before this material universe was created and will continue to exist after the end of this material universe.
So, Christ Jesus gave a teaching, saying "what is the use for conquering the material universe and becoming the king of the whole universe (which is finite)?" And, He said that whoever believed in Him and the God could be given eternal life."
The choice before us is between finite lengths of time (a tiny part of 13.8 billion years) and eternity (where 13.8 billion years is nothing). And it is the faith to believe that the God will surely hear our prayers while we live in only a short period of time in this finite universe.

Joh:12:11: Because that by reason of him many of the Jews went away, and believed on Jesus.
