One of the things that really bothers me about society is its segmentation of ages or life stages. Rod over at Crunchy Con has posted a letter from a single woman who can't find her way into the society of fellow crunchy cons because she is single. This is such a shame, particularly when most crunchy con's are people of faith. While society continues to fragment itself, the church should be moving in the opposite direction; building unity by having the old teach the young, letting the young aid the old, and everyone sharing their gifts with one another because we are all members of the body of Christ.
There is so much that needs to be done to rectify this, but one thing that could help would be to offer hospitality. Inviting someone to one's home who does not share the same station is a good start; whether they be older, younger, married, single, richer, poorer, working class, white collar, professional, etc... Hospitality is a command given to all Christians, and is even listed as a qualification to be an elder in the church, yet it seems to be one of those "old-fashioned" commands that is easy to ignore.
While not a cure-all, it could be a start. If you have any other suggestions, please add them in the comments.
