Someone asked me, "What happened to So-and-so? She hasn't been here for a long time." Sometimes, it's summer. Sometimes, it's job or personal circumstances. Sometimes, it's other stuff. All kinds of things can get one off-track, and then, if you don't get right back at it, the break in your worship discipline can become the new normal.
And who is the right person to ask? I ask when I see folks, and I'm sure others do, too. But for every person, there is probably at least one other who is the "right" person to ask -- who stands a chance of getting the right reaction to get them started back in attending regularly. Who is that person? How many "that persons" are there? Can we get them organized and send them out in reconnaissance parties? What does it take?
I've now been at this for a long time. I've seen a lot of people come, and -- to my sorrow -- I've seen a lot of people go. I wish I knew how to round up all the strays and love them so as to keep them where they belong.
