Literacy and Scripture

Note Scripture (incl. Revelation) was written for average illiterate people to understand it. Remember most people never had schooling or education until USA was a nation, and education was expanded in modern 1960s'- 80s [before then most only had a 6th or 8th grade education]. In 60s to 80s many were now going to High School. Colleges prior to 1960's were only for Pastors to get theology educations to preach at churches. As everyone prior to WW1 and 2 just apprenticed their fathers job; family business. Since WW2 college and education expanded because of feminism and to help family finances.

Knowing most in past history and even in many 3rd world countries today are still illiterate... so

1. God wouldnt write the Bible esp end times info to be complicated. Every believer was wanting to know about the return of Christ and when we would be free from this corrupt existence. 

2. Relevelation flows rightly & chronologically from Ch1 to the end. 

3. Jewish believers do not have a hard time understanding the Bible. Esp the ines in Apostles lifetime and 100 to 200 yrs later. The ones who have a hard time with Scripture in a general sense are Gentiles; non Israel Jews. Because it wasnt our culture and history. So we need Pastors to study all of that and present the Text of Scripture to us from wuthin the Biblical and historical proper interpretation. Not just in USA and the West but pastors in Asia and Africa and any other non English country that has access to eithet a Bible, Pastor or missionary. 

Those are the only reasons it takes us a long time to study the Bible. It has nothing to do some spiritually hidden mystery. God was clear with Christ the mystery of the ages was made clear. So too Revelation would be a very clear straight forward revelation. It isnt a parable hidden from the unbelieving Jews. It was written so believers would know what is coming and how the end will happen.
