"... Take to heart all these words I am giving as a warning to you today, so that you may command your children to carefully follow all the words of this law. For they are not meaningless words to you but they are your life..." (Deuteronomy 32:46-47 HCSB)
"For he is not a God of the dead, but of the living: for all live to him." (Luke 20:38 AKJV)
There is eternal life after this one. Jesus is the way to that eternal life.
