How come WELS pastors don't teach about the book of Revelation? I keep hearing we are currently living during "end times" and that it is near, but they don't expand on the teaching of the book. If I'm living it, I want to learn more about it and it is too complex to understand on my own.
The book of Revelation is a subject of WELS teaching and preaching. It is not a book of the Bible that we ignore. If your church has not offered a Bible study on the book of Revelation in some time, do talk to your pastor about that.
If you would like to read what some WELS pastors have written about Revelation, this link will provide you with plenty of good reading material.
In addition, this link will show you what materials on Revelation are available from Northwestern Publishing House.
