The Word must be rightly divided because of the gradations of revelation found in the different covenants.
The most profound distinction is between Law and Grace.
When studying the Word, we must understand the OldTestament in the context of the NewTestament. We search the OldTestament scriptures for evidence of Christ who brings salvation Joh 5:39. When we study the NewTestament we grow in Grace and knowledge of Christ Jesus 2Pe 3:18.
When you see the real object its shadow is no longer informative and should not be one`s focus.
Furthermore, understanding that Jesus was an OldTestament prophet is critical to balance His commands with His provision of Grace through His death and resurrection.
We are to be workmen, meaning we have a job to do for the KingdomOfGod. The WordOfTheLord is the tool we use to effect the Lord`s will. But having the true nature of the HolySpirit in our minds is necessary for good fruit to manifest.
Our study of the Word reveals that we are already approved of the Lord. We are AcceptedInTheBeloved.
