I think you have given a lot of wisdom in what you wrote. However I would tend to think that if a younger man is making disciples then he will continue to do that the rest of his life. I see the problem among many my age is they talk about retirement, their home, and health. What kind of a life is that to be born, work and die. Too many my age treat the church as a job they once did. Christ's church is more than just a building and work to maintain it but a living breathing organism of people trying to glorify God in all they do. Now that I am older I see things as even more urgent than ever. I meet with students whose parents are about ten years younger then me. I have not heard any of them complain about the help they are getting and following me in ministry. The times I ever hear complaints is when the older do not engage them in ministry and whatever they are doing. Young people want high quality leadership who are loving for Jesus not some kind of mediocre stand around and watch.When the church loses its respect for our older members because we cannot get our agenda through then we have lost sight of what a church is as a whole and the church is now a reproach. We need to remember that the word of God speaks favorably of our older generations (Pro 16:31). Maybe we need to spend as much time if not more trying to understand the older generation as we do running out and trying to understand the lost culture. If nowhere else, understanding ought to begin in the church first and foremost even if we “think” the older generation is not trying to understand anyone else.
We need to recognize that there is a vast difference between a generational gap and carnal minded Christians. The latter come in all sorts of stripes and colors and it is in error to assume the older generation is being carnal minded just because they do not immediately buy into what is new and presented as “culturally relevant”. This “cultural relevance” does more to divide people in our churches than anything else these days. We need to honor our older congregants just as much if not more than the world’s culture. Let’s get back to treating our older congregants with the love and respect they deserve.
When I was much younger the man who got me started in business also led many others in making disciples. There were about 1200 at his funeral. Some of the businesses in town shut down for the funeral. Some of the city leaders were there. His wife told me that there were people there she did not know. The funeral lasted for about three hours with person after person who stood and told about how he impacted their life. I figured that about 1/4 to 1/3 of those who were doing ministry were there. So many are living for Christ missionaries and pastors today because of his life. Until he died at the age of 76 I got letters regularly from him asking about my spiritual life. Young peope were around him all the time. In that same church were people his age and younger who would complain about being neglected. I never heard that from him. He gave away 1/2 of his income. The funeral was paid for by a person he had built a home for and finished two weeks earlier. I had the privilege of living in his home for one year before I was married. Every day I think about his example to me of godliness and how he lived his life. He did not have time to spend on things that did not matter.
