John_C said:
In Chapter 21 Of Religious Worship, and the Sabbath Day , the Westminster Confession of Faith (WCF) cites the sound preaching, and conscionable hearing of the Word, with understanding, faith, and reverance as being one of the principles of Worship. The sermon is part of the Worship service.

It cites verse 2 Timothy 4:2, Preach the Word; be instant in season, out of season, reprove, rebuke, exhort, with all long-suffering and doctrine.

Other verses cited include: James 1:22; Acts 10:33; Matt 13:19; Heb 4:2; and Isa 66:2.

Does preaching the word necessarily mean preaching a sermon though? Can't we preach the word through dialogue or through other means rather than in the form of a speech or lecture?
