We have to think about our own death.
What we who are alive should keep in mind is that
The end of all people on this earth is death (Eccle. 7:2).
We should go to funerals rather than weddings to think about our own deaths.
As we ponder the end of life
We must think carefully how we should live the rest of our lives to please the Lord.
There will come a time when we will all have to get off the train at the terminus of all our life trains.
