I have been reading an excellent book, Seeing and Savoring Jesus Christ by John Piper. This book really directs your heart and mind toward Jesus Christ. It highlights the revelation of the character, worth, and glory–indeed beauty–of Jesus Christ given to us in the gospels. The chapters are short and devotional. But they are very thought-provoking and would provide excellent fodder for extended meditation. I encourage you to add this book to your bookshelf too!
Update: This book is also available to read online here!
