2 Timothy 3:16 — All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,
Ephesians 4:14 — that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting,
2 Timothy 4:2-3 — Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers;
Titus 1:9 — holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict.
