The Word of God

"The Word of God alone is to be preached, in its perfection and inner consistency. Scripture is the exclusive subject of preaching, the only field in which the preacher is to labour. 'They have Moses and the prophets; let them hear them' (Luke 16:29); 'The scribes and the Pharisees sit in Moses' seat [that is, they teach the doctrine of Moses, which they confess]. Therefore whatever they tell you to observe, that observe and do' (Matt. 23:2-3)."

"The Word of God is God's wisdom revealing from heaven the truth which is according to godliness. 'But the wisdom, which is from above is first pure...' (James 3:17); 'Paul, a bondservant of God...according to...the acknowledgement of the truth which accords with godliness' (Titus 1:1). The exceptional qualities of the Word, both in its nature and its effects, evoke our admiration."
