I am under contract with publishers for several books:
A Theology of Creation Care (Biblical Theology for Life; Zondervan) -- with my son, Jonathan Moo
A Theology of Paul (Zondervan)
Hebrews (Zondervan Exegetical Commentary on the New Testament)
Philippians (Biblical Theology for Christian Proclamation; Broadman & Holdman)
I have given up predicting when these books will be finished. The publishers have shown extraordinary grace to me as I have shot past deadline after deadline. At this point, I am just hoping to get them all finished before I "retire" from Wheaton (in ten years?).
I am also co-editor (with D. A. Carson, senior editor, Richard Hess, and Desmond Alexander) of a new NIV Study Bible that should be appearing in the Fall of 2015.
