Church is a family. A family is made up of parents, kids, grandparents, pet dogs, rats, and chinchillas, stray cats, aunts and uncles, and long lost relatives. The church is a lot like a family. You don't get to pick who's in it. And that can be exciting and it can also be a real challenge. I always felt bad for a distant relative that always seemed lost to the rest of our family. Maybe due to life circumstances, they were pushed to the outer banks of the family. I'm not sure what actually happened. I was too young to know the real story but it broke my heart. I remember secretly wishing this distant relative and their family could have what we had. But that was never going to happen for lots of reasons. Now to the church. There are no strays, no outsiders, and no more advantageous roles to play in the church. Where you are in life is as Paul said, a good place to be. In I Cor. 7, he says over and over again, "remain as you are." If you are married, focus on that. If you are single, that's just as valuable. If you are widowed, you play a role too. You don't have to play another role other than the one God has given you right now. Your status doesn't change the fact that God values you as part of His family.
