Desiring God is a website and ministry led by well-known pastor and author John Piper.  The link here takes you to a specific part of the Desiring God website called Look at the Book.

In this section of the site, John Piper does verse by verse expositions of the Bible in a very concise and detailed way. Not only is this a very complete look at many passages of the Bible, it is also a great instruction manual on how to do hermeneutics when approaching God’s Word.

Hermeneutics you say? What is that? Simply, it means interpretation.  Biblical Hermeneutics then, is the study of how we study and understand the Bible. What Piper does in this section of Desiring God is show you by his own teaching how one should interpret the Bible (letting the Bible interpret the Bible).
