Even your eschatological view of the "last days" is only one of 4 different eschatological viewpoints.
I don't necessarily agree we are in the end times. Just because the US is falling, doesn't mean the gospel won't take off in many countries, from Asia to Muslims in Indonesia and the Middle East. Dispensationalism is about as far from the truth of the Bible you can get.
I went to Dispie churches for 15 years. It wasn't what I was reading in my Bible. But I kept my mouth shut, for fear of being called a heretic, even though whatever you believe about end times has NOTHING to do with salvation.
What I learned in Seminary, was that there are 4 eschatological viewpoints. I studied and read source material, plus opposing material. In the end, I realized I had always been Amillennial, I just had not known the name. It matched what I had been reading in my Bible for 25 years, at that point!! (Still does!)
All you learn is what you are taught in church, by someone who has no biblical training either. Even if you Google things, I'll bet you don't listen to sermons that are different than what you believe. And that applies to many aspects of Theology. I am Reformed in soteriology. It fits what I have read in the Bible, learned in seminary, and even my personal experience of salvation. Although I was taught Arminianism for 15 bad years. I got to see all the viewpoints in seminary, which included a few others besides Arminian and Reformed views of salvation, too!
Our professors didn't tell us what to believe at all! They told us to read the Bible, read the literature and figure out what we believed, because we were going to have to understand what and why we were preaching something. We did a series on Rev., and all the members of the preaching team had the same view. So, we preached verse by verse and showed why we believed what we did. It was a good series.
We all went to different seminaries, but the Biblical standard was the same. Very conservative, and relying on the Bible. But with some useful tools for studying the Bible, especially hermeneutics, but also the original languages, too.
If you have never been to a conservative, Bible believing seminary, then don't knock it. Studying the Bible increases my love for God and his people. It has given me tools to evangelize, to teach and preach, and also to write about my ministry, to inspire others.
There is a whole world of broken and hurting people, and I am gaining skills to help those people. You should do what God calls you to do. If he doesn't call you to seminary, then don't go! But don't put those of us down, that God has called and we have obeyed and are bearing fruit!!
