God would not have commanded us to rightly divide the word of truth if the word of truth did not have natural or simple divisions. That 90% of all other versions change the word study and the phrase "rightly dividing the word of truth" means that someone doesn't want believers to do it. That majority of professing Christians are turned off by right division is proof that they have succeeded.
In this study, we look into the Who, the What, and the Where in God's dealings in the whole Bible. The devil, when he tried to tempt Jesus in the wilderness used Bible doctrine against Jesus. It is important to be Biblical. It is important to be doctrinal. Those two, however, are not enough. We need to rightly divide the word of truth.
