Dallas Willard’s book The Divine Conspiracy is a masterpiece! It’s one of those books you finish reading and you think… “I need to read that again.”

It’s not the easiest read you will ever pick up. It’s challenging but absolutely worth.
(PS: It may be a bit difficult for the average student prior to college, just a heads up.) 

This book, a long with a few others from Dallas Willard I would highly recommend. 
Check out Dallas on Amazon…

I also found this page on GoodReads that is full of stellar Dallas Willard quotes. Go read a few for some more inspiration! Here are a few I found... 

“The aim of God in history is the creation of an all-inclusive community of loving persons,
with Himself included in that community as its prime sustainer and most glorious inhabitant.” 
― Dallas Willard

“The greatest issue facing the world today, with all its heartbreaking needs, is whether those who, by profession or culture, are identified as ‘Christians’ will become disciples – students, apprentices, practitioners – of Jesus Christ, steadily learning from him how to live the life of the Kingdom of the Heavens into every corner of human existence.” 
― Dallas Willard, The Great Omission: Reclaiming Jesus's Essential Teachings on Discipleship

“We must understand that God does not "love" us without liking us - through gritted teeth - as "Christian" love is sometimes thought to do. Rather, out of the eternal freshness of his perpetually self-renewed being, the heavenly Father cherishes the earth and each human being upon it. The fondness, the endearment, the unstintingly affectionate regard of God toward all his creatures is the natural outflow of what he is to the core - which we vainly try to capture with our tired but indispensable old word "love".”

“Sabbath is a way of life (Heb 4:3; 9-11). It is simply "casting all your anxiety on Him," to find that in actual fact " He cares for you"
(1 Peter 5:7). It is USING the keys to the Kingdom to receive the resources for abundant living and ministering.”
