Everyone will be forgotten, nothing we do will make any difference, and all good endeavours, even the best, will come to naught. Unless there is God. If the God of the Bible exists, and there is a True Reality beneath and behind this one, and this life is not the only life, then every good endeavour, even the simplest ones, pursued in response to God's calling, can matter forever.
