There is a center to the Bible and its message of grace. It is found in Jesus Christ crucified and resurrected. Grace, therefore, must be preached in a way that is centered and focused on Jesus Christ Himself. We must never offer the benefits of the gospel without the Benefactor Himself. For many preachers, however, it is much easier to deal with the pragmatic things, to answer "how to" questions, and even to expose and denounce sin than it is to give an adequate explanation of the source of the forgiveness, acceptance, and power we need.
It is a disheartening fact that evangelical Christians, who write vast numbers of Christian books, preach abundant sermons, sponsor numerous conferences and seminars, and broadcast myriad TV and radio programs actually write few books, preach few sermons, sponsor few conferences or seminars, and devote few programs to the theme of Jesus Christ and Him crucified. We give our best and most creative energies to teaching God's people almost everything except the person and work of our Lord and Savior. This should cause us considerable alarm, for there is reason to fear that our failure here has reached epidemic proportions. We need to return to a true preaching to the heart, rooted in the principle of grace and focused on the person of the Lord Jesus Christ.
