“Look at it this way. If someone has a hundred sheep and one of them wanders off, doesn’t he leave the ninety-nine and go after the one? And if he finds it, doesn’t he make far more over it than over the ninety-nine who stay put? Your Father in heaven feels the same way. He doesn’t want to lose even one of these simple believers.” - Matthew 18:12
If this is the heart of the Father Himself then how much more should we not make it our mission to look after church members who we may not have seen recently at church? At times it may mean "going after" the inactive church member to check in and see how they are really doing.
