Our great-grandparents all knew that “Who You Belong To” was the most important thing about you. So did nearly everyone else in the preceding 10,000 years. That knowledge was lost among the elite during the Enlightenment and among the masses beginning with the industrial revolution. We are now immersed in a culture today that believes in autonomy and individualism and cuts ties with others fairly routinely. Community and Covenant are now quite foreign terms.
The importance of whose we are has also been known by contemplatives and 
mystics for at least 3,000 years, who spend a great deal of time getting closer to God and building their relationship with Him. Dallas Willard understood this and blazed a trail back to what it means to have an interactive relationship with God that is strong enough to transform our lives.
Neurology has now verified scientifically what everyone used to know. But it did not establish or discover this reality. The idea that we need to add brain science to the biblical record in order to have a proper perspective is simply not supported by history or even the Bible itself.
Covenant is God’s term for “Whose We Are.” The theology, implementation and practice of covenant are among the most important themes in all of Scripture. We might not grasp the meaning of covenant very well today, but it is how Scripture defines “our people.”
The two greatest commandments point us toward attachment and bonding. Jesus also told his disciples, “We will come to you and make our home with you.” The term abiding is one of the words Jesus used to describe our relationship with Him. The “ministry of reconciliation” of which Paul wrote is all about coming into union with God and people. From one end to the other, the Bible is all about the relationship between God and human beings living together in the bonds of love.
More to the point, Dallas was not only aware of all of this, it was the very focus of his writing and teaching that a relationship with God is available to all of us, that this relationship goes far beyond having “right” doctrine and ideas about God, and that we can intentionally go about building this relationship.
