Jim Jack, if you want to know about awesome teachers and people who do awesome things, I'd love you to come with me to either of the two churches I regularly attend, spend time with the ministers there and with the congregations, and come out with us on some of our many and varied genuine outreach and assistance events. You will find many who walk the talk, and talk the walk.
There are many people who are worthy of national and international respect, genuine scholarship, genuine very high level appointments (one is chaplain to the Queen), one is a peer of the realm (a genuine aristocrat) - and all are so humble, quiet, gentle, and inclusive. There are no TV evangelists, but from time to time the BBC broadcasts the Easter or a Christmas service from Bath abbey (where the Queen's chaplain has his "regular job" as the Rector of the abbey) and the rector is the nicest man who really points the way to Jesus and honours God. You want what he's got, not because he "sells" it in loud manner, but because of his quietness, peacefulness and confidence in the Lord. The peer has set up many programs to assist homeless and vulnerable people and is a real "mover and shaker" to get things done that bring Christ to the overlooked, and to build Christian unity among believers. Yet he's so self-effacing that he is easy to overlook. I know of several who have given land or large amounts of money for community projects (it's taken me a long time to find this out because they don't shout about it). I know people who have very little in financial terms, but spend their time and energy tirelessly doing things that benefit their community, because of their love for Christ and their desire to show that love.
In fact, I could write a very long list of awesome but very humble people that I meet through these churches and the other very active churches, of all denominations, throughout this city.
Jim Jack, I can arrange meetings for you with some mightily awesome Christian folks, who from genuine Christian love seek the wellbeing of their community in a huge variety of ways. I can't promise splashy miracles. I can promise genuine heart and genuine and observable turn-round in a myriad of ways, in people's lives.
Please let me know when you would like to come with me.
