“But truly I am full of power by the Spirit of the LORD, and of judgment, and of might, to declare unto Jacob his transgression, and to Israel his sin.” Micah 3:8 (KJB)
The prophet of God is called to give the “whole counsel of God” (Acts 20:27) whether that be good and positive, bad and negative. The preacher of today if called by God is called to do the same.
At times the preacher is given a message of comfort, hope, encouragement, and strengthening of faith. At other times he is given a message of judgment, and can cause, by the Spirit of the LORD, great fear and trembling and should lead the people to repentance, and faith toward Jesus Christ.
Micah’s message seems to be a doom and gloom message at the beginning, but as you read on into the message there is hope, blessing, encouragement, and words to strengthen one’s faith.
If the prophet is only defying the truth of God’s word, leaving out the warnings, the judgments, the negatives; then that prophet/preacher is not worth listening to; and you better go somewhere else. They are not a man of God.
We can certainly judge what the preacher says and/or does not say when we read the Scriptures. The Bible is our guide; our only source for judging what is true and right; or what is lies and deceiving.
When in doubt you can trust the words of the Lord Jesus when He said, “Judge righteous judgment” (John 7:24).
