If I was asked what is the most valuable thing I have learned in my recent years of study, I would say something similar to what D. A. Carson recently wrote:
I have spent much of my adult life working through the way the New Testament quotes the Old, and the longer I ponder these texts, the more I begin to see how they “work,” how rich and beautiful are the ways in which God ordained that his great plan of redemption would be prefigured in an extraordinarily rich, complex, and intertwined array of promises, types, trajectories, histories, institutions and persons, working together to point forward to Jesus and his gospel.
The way that Scripture works boggles the mind and brings great joy to the heart. I commend it to you for your reading enjoyment.
