I do not have an answer to that question. Yet. I stuck my toe in that water for a few minutes this morning in Logos by doing a surface word study on the use of chosen in the New Testament and the Septuagint, looking at what Hebrew words were translated with chosen. There was a significant amount of data. To answer the question more accurately, I need to evaluate that data. It is a whole lot like work, albeit work that I love.
Too often I have approached the scripture like I did with the note on Lamentations 2:5, I have also observed many believers doing the same thing, pastors and leaders included. 2 Timothy 2:15 tells us that we are to be diligent with the Word of God. There is a process here. It is like a journey; encapsulated in my experience with Lamentations 2:5. I need to remind myself daily to hold what I “know” to be true lightly, always being ready to turn that knowledge into a question, which answer is dependent on the data in the Book that has no bottom.
