The document discusses the theology of effectual calling according to the Westminster Confession. It explains that (1) God effectually calls only the elect to salvation, (2) this calling involves God regenerating the person and making them willing to respond to the gospel, and (3) God's election and calling applies even to those unable to respond externally, like infants. It also notes that (4) some who are outwardly called through the ministry of the Word will ultimately fall away and not be saved.
