                                                Sacrifice

                                          When he has more than he can eat
                                            To feed a stranger's not a feat.
                                        When he has more than he can spend
                                              It isn't hard to give or lend.
                                          Who gives but what he'll never miss
                                            Will never know what giving is.
                                          He'll win few praises from his Lord
                                          Who does but what he can afford.
                                           The widow's mite to heaven went
                                           Because real sacrifice it meant.
