Last night we studied the Feast of Trumpets from Leviticus 23:23-25. During the sermon we considered the strong comparison between the Old Testament trumpets announcing God's presence, reign, and voice, and the New Testament practice of preaching, also announcing God's presence, reign, and voice. One of the basic lessons was that preaching matters. Through preaching God meets his church, rules his church, and speaks to his church.
The same point is made by William Taylor in his introduction to the St. Helen's Bishopsgate (London) monthly video series, Preaching Matters. You can see the introduction to the video series below. Whether you are a preacher or not, I'm sure you have much to gain by checking out this helpful series.
