Confessional orthodoxy coupled with a view of a heavenly Father whose love is conditioned on his Son’s suffering, and further conditioned by our repentance, leads inevitably to a restriction in the preaching of the gospel. Why? Because it leads to a restriction in the preacher that matches the restriction he sees in the heart of God! Such a heart may have undergone the process that Alexander Whyte described as “sanctification by vinegar.” If so, it tends to be unyielding and sharp edged. A ministry rooted in conditional grace has that effect; it produces orthodoxy without love for sinners and a conditional and conditioned love for the righteous.
In the nature of the case there is a kind of psychological tendency for Christians to associate the character of God with the character of the preaching they hear-not only the substance and content of it but the spirit and atmosphere it conveys. After all, preaching is the way in which they publicly and frequently “hear the Word of God.” But what if there is a distortion in the understanding and heart of the preacher that subtly distorts his exposition of God’s character? What if his narrow heart pollutes the atmosphere in which he explains the heart of the Father. When people are broken by sin, full of shame, feeling weak, conscious of failure, ashamed of themselves, and in need of counsel, they do not want to listen to preaching that expounds the truth of the discrete doctrines of their church’s confession of faith but fails to connect them with the marrow of gospel grace and the Father of infinite love for sinners. It is a gracious and loving Father they need to know.Sinclair Ferguson, “The Whole Christ” pg 72
