I just finished reading Albert Mohler's blog for today - Dying without God, The Absence of Belief at Life's End.
I highly recommend that you read it, especially in the light of recent polls that show that more and more America is becoming a non-religious country. I see this trend more and more in my students.
I'm filling in for my pastor in a couple of weeks, preaching on a few verses from the middle of Psalm 103. These verses speak of the shortness of human life. Without giving away my sermon (come back in a few weeks for that), human life is short and all of us will soon be forgotten. My hobby is family history - unearthing the details of the live of people who are long gone. It's exciting to find the details, yet most of the information about people will never be remembered. Nor does it even exist. The knowledge of all those people simply doesn't exist anymore. Only the bare bones about them is left - death, wills, locations, marriages, children, birth or christening. Many times these are gone as well. We know nothing of their hopes, dreams, aspirations, desires, personalities or even their looks.
So what does this have to do with death - mine, or yours? Simply this. Our greatest evangelistic tool may (should?) be the fact of death and what happens after. What happens to the human after death? There aren't many options, and most of them deny ultimate human significance. I'll be exploring this more in the near future. My thesis will be that if there is no God to meet after death, then there is no ultimate human significance.
