Insufficient challenges pastors to look at their work in its varied complexity while recognizing the need and demand to increase competency in skills. Pastors must admit their "insufficiency." Nabors does not shy away from calling pastors to realize there is more than meets the eye in pursuing ministry. A right pursuit of orthodoxy has sometimes blinded pastors to what has been left out, namely the articulation of orthopraxis. Pastors need Christian good works, especially justice and mercy. This orthopraxis is an essential part of any true, orthodox theology. This work is daunting and difficult. Insufficient calls pastors to a dependence on the grace and power of the Holy Spirit, who alone is able to make competent pastors of the Gospel. Nabors provides insights, advice, and pragmatic wisdom from more than forty years of ministry experience.
