If you want to study Christology (and you should), then here’s a book to add to your reading list:

Robert A. Peterson. Salvation Accomplished by the Son: The Work of Christ. Wheaton: Crossway, 2012. 619 pp.

John Frame, professor of systematic theology and philosophy at Reformed Theological Seminary in Orlando, says this of the book:

Dr. Peterson told me in correspondence, “my work is not [systematic theology] as much as laying biblical foundations for systematics.” Well, people can define terms as they like. But I think Salvation Accomplished by the Son is systematic theology at its very best. It deals with doctrines of systematic theology by bringing them into closest proximity with the biblical texts that justify them. That is the kind of systematics of which we need much more. This is the book to which, after Scripture itself, I would first turn to explore any question about Jesus’s incarnation, atonement, or resurrection.
