Having recognized the primacy of the word in God's own dealings with the human race, it is not at all difficult to note the primacy of the word in that early Christian preaching recorded in the New Testament.
Peter's great sermon given on the day of Pentecost is an example. Peter and the other disciples had experienced a visible out pouring of the Holy Spirit, manifested by the sound of a rushing mighty wind and tongues of fire that had rested on each of the disciples (Acts 2:1-3). They had begun to speak so that others heard them in a variety of languages (v. 4). In addition to this, they had all just been through the traumatic and then exhilarating experiences of the crucifixion, resurrection, visible appearance, and ascension of the Lord Jesus Christ. These were heady experiences. Yet when Peter stood up to preach on Pentecost, he did not dwell on his or anyone else's experiences, as many in our day might have done, but rather preached a profoundly biblical sermon centered on specific biblical passages. The format was as follows: First, there are three verses of introduction intended to link the present manifestations of the outpouring of the Spirit to God's prophecy of that even in Joel. These were a lead-in to the major text. Second, Peter cites the prophecy in Joel at length, giving a total of five verses to it. Third, there is a declaration of the guilt of the men of Jerusalem in Christ's death, which, however, was in full accordance with the plan and foreknowlege of God, as Peter indicates. This takes three verses. Fourth, there is an ex tended quotation from Psalm 16:8-11, occupying four verses. These stress the victory of Christ over death through his resurrection and exaltation to heaven. Fifth, there is an exposition of the sixteenth psalm, occupying five verses. Sixth, there is a further two-verse quotation from Psalm 11:1, again stressing the supremacy of Christ. Seventh, there is a one-verse summary.
