It takes work to rightly divide the Bible.
First, read about and know all God’s revelations in the Bible. Right division is impossible with a single revelation.
Second, discern what and what manner of time God was speaking. This is called dispensational Bible study.
Third, rightly divide the differences created by God’s dispensations. If you can’t find any differences go back to step one.
Salvation is not of works, but we grow spiritually according to the work we put in to studying and applying the Bible rightly divided.
Rightly dividing the Bible takes work. We were made to be workmen (Eph 2:10).
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth (2 Tim 2:15).
For His glory,
Justin “work” Johnson
