Now, that's a great question, and one I have been pondering, since March (2013)
In my 1st "vision/dream", I was in an auditorium filled with Christians, and Jesus told me, things to tell them, and 7 items to reiterate to fellow Christians. One of them (but not one of the 7 items) was to tell Believers, that even Murderers could go to Heaven, by Accepting His Free Gift of Salvation, they didn't like that idea a bit. Sin is Sin, whether it be Adultery, Theft, or Murder, they All fit, in His eyes, as Sin. Therefore, if by Accepting His Free Gift of Salvation, All their Sins are Forgiven, then they are, Forgiven.
He knows, I have been writing "poetry sermons" (not my label, but from others), for many years now, accumulating over 100 now.
He knows, that He has planted ideas and understandings, that I have been "bursting at the Biblical seams", to get His Message out, to both Believers & the Lost.
Yes, the ideas He has shared with me, stay within the boundaries of the Southern Baptist Church, but they are both to get Believers to understand their role, but also, to share with the Lost, why it's important for them to Believe, and join Us, as "Children of God".
Now, I can't do any of this, sitting in a pew, listening to my Pastor. I can't do any of this, sitting in a Sunday School classroom, listening to its' Teacher.
Question for you (or anyone else): When was the last time, you walked into an area full of people, and asked them, "Do all of YOU know, if YOU should die today, where YOU would spend Eternity?" or "Do YOU, Children of God, know what your obligation is to God, besides simply Accepting His Free Gift of Salvation?"
God wants Us, to step out of our Comfort Zone, and get at the front lines, speaking both to the Believer and the Lost. Instead of sitting back, and assuming someone else will do it.
So, yes, I do believe Jesus wants me to be a Pastor, but also so much more. Not simply to talk to my own congregation, but to get His Message out, to the entire World, by any means available.
His subsequent "visions/dreams" were basically asking me, Why I haven't gotten started.
After all, I don't want to put Him off, and end up "inside the belly of a whale", if you know what I mean.
