Currently I am reading "Engaging God's World" by Cornelius Plantinga Jr. It is a great read for any Christian seeking purpose behind their education or vocation. Plantinga encourages the reader to look at everything in the world through the meta-narrative of Scripture (Creation, Fall, and Redemption), and challenges the elected (Christians) to faithfully take part in the gracious opportunity to be an agent of reformation. Plantinga's running challenge through the whole book is, wherever you are and whatever you are doing, to strive and pray for the Lord to bring the Kingdom of God.
Similar read would be one of my favorite by Albert Wolters, "Creation Regained."
