I read this in John Piper's new book, What Jesus Demands of the World. Piper writes in Demand #9 (pg.75), Love God With All Your Heart, Soul, Mind, and Strength:
Jesus came to RESTORE human beings to the kind of relationship with God and each other that we were created for. The most important thing he has to say about that RESTORED relationship with God is that we were meant to love God with all our heart and soul and mind and strength.
This whole concept of RESTORE and RESTORATION is one that I've been praying about the last couple of days. Hopefully I'll be able to tell you why soon.
Piper quotes the following scripture:
...answered Jesus, "is this: Hear, O Israel, the Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength." Mark 12:29-30 (NIV)
"Woe to you Pharisees, because you give God a tenth of your mint, rye and all other kind of garden herbs, but you neglect justice and the love of God. You should have practiced the latter without leaving the former undone." Luke 11:42 (NIV)
"I know you do not have the love of God in your hearts. I have come in my Father's name, and you do not accept me; but if someone else comes in his own name, you will accept him." John 5:42 (NIV)
Piper's point: Jesus demands that we love God above all else. God will reciprocate and restore us to a right relationship with Him.
The book is vintage Piper and therefore I am learning a ton.
