One of disparities between apostolic preaching and our own is the degree to which we have marginalized the gospel. We have not abandoned the gospel, only relegated it to the outskirts of our Christian experience. As a result, the message of the cross is primarily reserved for those who are on the threshold of faith. The gospel has become one of the “elementary truths” believers expect to “leave” when they are ready to “go on to maturity” (Heb. 6:1).
This is a conviction shared by our listeners, whose hearts often sink if they suspect that the sermon is “just a gospel message.” The gospel is something they have already heard. They believe and appreciate it. But now they want to learn about the God who gave the gospel. They do not want to be like those about whom the writer of Hebrews complains, who should have been teachers but needed someone to teach them the elementary truths of God’s word all over again.
These assumptions, while understandable, are problematic. It is true that there is more to God’s word than the gospel both theologically and practically. The horizon of subjects upon which the Bible touches is as wide the scope of human experience. Its concerns span all the theological categories from theology proper to eschatology. But if our goal in preaching is for people to know God, it must be asked whether this is possible in any meaningful way apart from the gospel.
Preaching, since it has to do with God, is dependent upon divine self-revelation. We could not know anything about God if he had not taken the initiative to reveal himself. It is, of course, possible to know things about God apart from Christ. The heavens declare the glory of God. Our consciences reveal his eternal power and divine nature. But it is not possible to know God relationally except through Christ. The God who in the past spoke to our forefathers through the prophets at many times and in various ways, has in these last days spoken to us through his son (Heb. 1:1-2). Jesus is God’s final and best word about himself. This side of the incarnation, all that we know about God must be seen and understood through the lens which Christ provides.
