WLC Q.68: Are the elect only effectually called?
All the elect, and they only, are effectually called: (Acts 13:48) although others may be, and often are, outwardly called by the ministry of the word, (Matt. 22:14) and have some common operations of the Spirit; (Matt. 7:22, Matt. 13:20–21, Heb. 6:4–6) who, for their willful neglect and contempt of the grace offered to them, being justly left in their unbelief, do never truly come to Jesus Christ. (John 12:38–40, Acts 28:25–27, John 6:64–65, Ps. 81:11–12)
Others, not elected, although they may be called by the ministry of the Word, (Matt. 22:14) and may have some common operations of the Spirit, (Matt. 7:22, Matt. 13:20–21, Heb. 6:4–5) yet they never truly come unto Christ, and therefore cannot be saved: (John 6:64–66, John 8:24) much less can men, not professing the Christian religion, be saved in any other way whatsoever, be they never so diligent to frame their lives according to the light of nature, and the laws of that religion they do profess. (Acts 4:12, John 14:6, Eph. 2:12, John 4:22, John 17:3) And to assert and maintain that they may, is very pernicious, and to be detested. (2 John 9–11, 1 Cor. 16:22, Gal. 1:6–8)
