In Brennan Manning’s book, “The Furious Longing of God” he talks about a how Paul mentions that Jesus “emptied Himself” for us. The following is taken from his book on page 124-126.

“He cried from His heart, nails in His hands, and poured out His blood that we might believe His love for us. Significantly, Jesus chose the giving tree, His cross, as the demonstrative sign of His absolutely furious love from men and women. In the words of one early church father: ‘the mightiest act of love ever to arise from a human soul.’

How is it then that we’ve come to imagine that Christianity consists primarily in what we do for God? How has this come to be the good news of Jesus? Is the kingdom that He proclaimed to be nothing more than a community of men and women who go to church on Sunday, take an annual spiritual retreat, read their Bibles every now and then, vigorously oppose abortion, don’t watch x-rated movies, never use vulgar language, smile a lot, hold doors open for people, root for the favorite team, and get along with everybody? Is that why Jesus went through the bleak and bloody horror of Calvary? Is that why He emerged in shattering glory from the tomb? Is that why He poured out His Holy Spirit on the church? To make men and women with better morals?

 
The gospel is absured and the life of Jesus is meaningless unless we believe that he lived, died, and rose again with but one purpose in mind: to make brand new creations. Not to make people with better morals, but to create a community of prophets and professional lovers, men and women who would surrender to the mystery of the fire of the Spirit that burns within, who would live in ever greater fidelity to the omnipresent Word of God, who would enter into the center of it all, the very heart and mystery of Christ, into the center of the flame that consumes, purifies, and sets everything aglow with peace, joy, boldness, and extravagent, furious love. This, my friends,  is what it really means to be a Christian. Our religion never begins with what we do for God. It always starts with what God has done for us, the great and wondrous things that God dreamed of and achieved for us in Jesus Christ.”
