There is an interesting scene in a movie called "The Postman". This movie is set in the future where society has broken down. Instead of democracy there is a feudal system in place where man named General Bethlehem uses fear to keep people in line.
At one point, after a group of people have reinstated the postal system, the generals's men get hold of a bag of mail, . They think it is nothing, just letters about family, or seemingly unimportant news. But the general is furious as he tells them "it's not nothing, it's everything."
What the General fears is communication and unity, which is what comes from sharing lives together. All the little seemingly insignificant details we share help build community.
The enemy, like General Bethlehem, would have us in small pockets, isolated from each other. He does what he can to divide. But the church of Jesus Christ is a powerful force when united and strong.
"Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it." Matthew 16:17-18 (NIV)
