Blessed is the man who doesn’t walk in the counsel of the wicked, nor stand in the way of sinners, nor sit in the seat of scoffers; but his delight is in Yahweh’s law. On his law he meditates day and night. He will be like a tree planted by the streams of water, that brings forth its fruit in its season, whose leaf also does not wither. Whatever he does shall prosper.
The idealism and self-sacrificing commitment of that wartime generation are harder to find in our society today. But as Christians, we are challenged to rediscover that commitment. Jesus is saying to his people today the same sort of thing Uncle Sam said in those posters. Jesus is saying to us, “Your church—my church—needs you!”
