"Expository preaching is a most exacting discipline. Perhaps that is why it is so rare. Only those will undertake it who are prepared to follow the example of the apostles and say, ‘It is not right that we should give up preaching the Word of God to serve tables. . . . We will devote ourselves to prayer and to the ministry of the Word’ (Acts 6:2, 4). The systematic preaching of the Word is impossible without the systematic study of it. It will not be enough to skim through a few verses in daily Bible reading, nor to study a passage only when we have to preach from it. No. We must daily soak ourselves in the Scriptures. We must not just study, as through a microscope, the linguistic minutiae of a few verses, but take our telescope and scan the wide expanses of God’s Word, assimilating its grand theme of divine sovereignty in the redemption of mankind."
