Hello,
Revelation 1:3 [i]"God blesses the one who reads the words of this prophecy to the church, and he blesses all who listen to its message and obey what it says, for the time is near."[/i] (NLT)
(A word of encouragment for you, brother!)
You're right. You're going to find practically as many opinions and theories as the number of people you ask. That's precisely why I'm not going to recommend any resources, websites, outlines or any books, except one. You already own it and you already love it. The Bible.
I'm not saying this to be "super spiritual" or in an attempt to sound "holier than thou." What I have to say comes from the deepest depth of my heart. Study this subject for yourself.
There have been debates on this subject since man could read. In all the debates I've witnessed, and even participated in, I've [i]never once[/i] seen anyone persuaded to change their viewpoint because of the debate. More importantly, what you're going to get from most of the resources that are recommended to you, are [i]people's[/i] opinions and theories based on [i]their[/i] study. Unfortunately, many times that study is done in their own efforts and without(much)prayer. Even people who say they've prayed have differing opinions. This is why it's important to study this for ourselves.
I say this because I have asked countless people how many of them have really studied the Bible (not other books or resourcs) and actually prayed diligently about this subject. I asked if they've heard from God on the matter so that it's a resolved matter to them. None could say they have.
We have the same Bible as the greatest theologians and eschatologists that ever lived. And we are as close to the Father as we want to be. God isn't a respector of persons. Honor God by studying the subject for yourself, through His Word and the Holy Spirit. Don't lean on the understanding of men. Study and pray and trust the Lord with all your heart.
