I think the long-term prognosis is indeed bi-vocationalism or tent-making if you will. The Church is going to have to, out of necessity, be willing to call, accept and pay part-time pastors for much longer periods than has been usual. Whether or not the online seminary phenomenon is a net gain or loss, it no doubt has contributed to a large increase in pastoral candidates. Are we willing to entertain the thought that a man could readily prepare for the ministry with the expectation that he will make tents for many years? In some ways this financially less dependent pastoral base could be a benefit to the church in many areas. If the expectations are clear, men be more likely to accept callings in more remote pulpits- domestic and foreign.
Perg has already mentioned the global southeast. What about Europe? How many Europeans (or South Americans) over the years, even in major metropolitan areas, have dropped by the PB starved for any church that can remotely be considered bible believing? One that is not 200 miles away? I suppose training for a "secular" vocation in order to live/work elsewhere while tent-making is a tall order. However, if the church's hand is forced by a Providential reduction in full-time calls, why not?
