Imagine living 2,000 years ago and your church received a letter from the Apostle Paul!
On Sunday, everyone gathers to hear the pastor read the letter received earlier in the week. As the letter is slowly read line-by-line, your pastor stops to explain each words and idea. It takes him a long time, even weeks or months, to read through every word of the letter and explain it so you fully comprehend.
Paul’s letter can’t be understood by reading a random line and then talking about something else. It must be read and studied just as he wrote it to your church, word-by-word and line-by-line. This is called expository preaching. If you want to understand the God of the Bible, and how to serve Him, attend a church where the pastor is an expository preacher.
So they helped the people to understand the Law, and the people stood in their place. So they read distinctly from the book, in the Law of God; and they gave the sense, and helped them to understand the reading (Nehemiah 8:7, 8).
