2 Timothy 3:16-17

v16a: The Scriptures are the Word of God. This is confirmed by "the majesty of its style, from the truth, purity, and sublimity of the doctrines it contains, from the harmony of its different parts, from its power and effectiveness on the minds of multitudes who have dealings with it, from the fulfilment of many prophecies about things beyond all human foresight, and from the... miracles that were performed to prove its divine origin."

v16b: What we find in God's Word "instructs us in what is true, rebukes us for what is wrong, directs us in what is good. It is useful to all, for we all need to be instructed, corrected, and rebuked."

v17: Pastors who have responsibility for giving "instruction, correction, and rebuke" in the church will find the Scriptures sufficient to equip them "for whatever duty [they] have to do,” and “whatever service is required from [them]."
