Relationship tool

We were eating dinner last night and were talking about the decline in membership of churches. (We are consultants specializing in ways to bring new life to an organization, repair relationships, and increase growth.) We were discussing a refinement of a tool that repairs and cements relationships that once learned operates transparently in our daily lives. Success is built on relationships. People seem to often build their relationship on the premise that as long as you can do something for me, in other words, have value to me, then we can get along. But as soon as I feel that you have nothing to offer that benefits me, I won't be associating with you. That is not a healthy relationship. What do you think a healthy relationship would look like?
