The irreligious don't repent at all and the religious only repent of sins. But Christians repent of their wrongfully placed righteousness.
Timothy KellerEveryone will be forgotten, nothing we do will make any difference, and all good endeavors, 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 endeavor, even the simplest ones, pursued in response to God's calling, can matter forever.
