God has commanded us to preach all of His Word and to "reprove, rebuke, exhort" (2 Timothy 4:2). This is the preacher's divine standard. God has commanded us not only to believe sound doctrine, but also to earnestly contend for it (Jude 3). That means we are to fight agrressively against that which is false. This is exactly what we see in the uncompromising ministry of the Lord's Apostles. Their epistles contain strong and clear warnings about false teaching. Paul often named the names of the false teachers. Such a ministry naturally causes divisions between those who are committed to the truth and those who are following error. Paul made no effort whatsoever to avoid doctrinal controversy. The Holy Spirit warned that "evil men and seducers shalll wax worse and worse, deceiving and being deceived" (2 Timothy 3:13).
