Prophecy, inspiration of OT

The prophecies of biblical messengers are acknowledged as being of divine origin, inspired through the activity of the Holy Spirit.

God speaks through his prophets

2 Peter 1:20–21 See also Nehemiah 9:30; Zechariah 7:12; Hebrews 1:1

Above all, you must understand that no prophecy of Scripture comes from one’s own interpretation. For no such prophecy was ever brought forth by the will of man, but men spoke from God as they were carried along by the Holy Spirit.

God is the source of prophecy

Ezekiel 24:20–21 The phrase “the word of the LORD came to ...” is frequently used of (and by) the prophets to indicate that the message they proclaimed came directly from God. See also 1 Samuel 15:10; 2 Samuel 7:4; 1 Kings 13:20, 1 Kings 16:1, 1 Kings 17:2; 2 Kings 20:4; Jeremiah 1:2; Ezekiel 6:1; Jonah 1:1; Haggai 2:10; Zechariah 1:1

So I answered them, “The word of the LORD came to me, saying: Tell the house of Israel that this is what the Lord GOD says: ‘I am about to desecrate My sanctuary, the pride of your power, the desire of your eyes, and the delight of your soul. And the sons and daughters you left behind will fall by the sword.’

Prophets inspired by God speak the truth

Deuteronomy 18:22 See also Jeremiah 28:9

When a prophet speaks in the name of the LORD and the message does not come to pass or come true, that is a message the LORD has not spoken. The prophet has spoken presumptuously. Do not be afraid of him.
