Well, I like the idea of what Jesus did. I mean, he went up a hill and preached to his followers that way, so can't I do that?
Remember Jesus didn't get paid for it, either. You can certainly preach that way and, I think, do much good in bringing people to Jesus. But if you spend all your time doing that, I think you have to be prepared for the kind of poverty Jesus enjoyed, too.
If you want preaching to be your occupation, and you want it to bring you enough remuneration to keep you in a modest but decent standard of living, then you have to convince people that what you're giving them is worth a bit of money now and again.
I think this sort of thing might be easier to do in America than in Scotland. I don't know anything about religiosity in Scotland, so I could be totally wrong. But here in America, I've met a lot of preachers who start up small but successful churches without having any formal, man-made training. They just have a gift of faith in Jesus and a gift to be able to transmit that faith to others. I've seen whole neighborhoods completely transformed by men like this, and it's absolutely beautiful to see. The preacher's influence is often not even known five blocks from where he preaches, but everyone within four blocks has powerful faith because of his ministry. It's incredible.
Being ordained by credible institutions makes it easier to convince people to compensate you for your time, but getting an ordination like that means you have to comply with the requirements of the credible institution ordaining you. That often means study.
I can understand your aversion to study. I've done a lot of studying in a lot of different fields, and I've found that unless I'm willing to put a whole huge amount of effort into studying, I almost invariably end up losing my own native intuitions about a topic and just become a blind follower of the latest fad theories in the field. I don't like that, but it's often just the way it goes. The first few years of study are devoted to tearing the student's preconceptions away and building a uniform foundation based on the prevailing theories of the time. Only in years of subsequent study do you get the chance to go beyond those prevailing theories, and that's when your native gifts finally resurface to inform your studies and the marriage of those native gifts with the many years of study can be truly wonderful and far more fulfilling than even your native gift alone. But to get there, you have to go through years of being a carbon copy of your professors and man's limited wisdom while your natural talent suffocates.
If you're going to study, study long. Drink deep or touch not the Pierian spring, and all that. Otherwise the fire you feel now and the talent you have now will get snuffed out. If you study long enough, eventually your natural talent will be directed into an unbelievably powerful force for Christ.
If you can't commit to many long years of study, then you might be able to do well in the kind of situation I described earlier if Scotland is as easy an environment for it as America is. Or you could just preach part-time and have some other job that lets you live, so that you can live to bring the gospel of Jesus Christ to his people.
If I were you, I'd get on my knees and ask God what He thought I should do. May God bless you in whatever you decide to do.
