GOD IS SLOW TO ANGER, GRACIOUS AND FULL OF COMPASSION
First of all, God never brings judgment because He enjoys punishing. Even in the Old Testament we see that God is a God who is gracious and full of compassion.
The LORD is gracious and full of compassion, Slow to anger and great in mercy. The LORD is good to all, And His tender mercies are over all His works.
- Psalms 145:8-9
We know the story, after three days in the belly of a fish God was able to persuade Jonah to go. So he went and delivered a fiery judgment message to the city of Nineveh.
But then what Jonah feared happened. The city repented, and this would make Jonah look like a false prophet, because he had only prophesied that it would be overthrown. He might have left out the point of repentance hoping that they then would not repent. But, according to the story, they did and It says that "...God relented from the disaster that He had said He would bring upon them, and He did not do it." (Jonah 3:10).
This displeased Jonah and in chapter four we see him complaining to God.
So he prayed to the LORD, and said, "Ah, LORD, was not this what I said when I was still in my country? Therefore I fled previously to Tarshish; for I know that You are a gracious and merciful God, slow to anger and abundant in lovingkindness, One who relents from doing harm.
- Jonah 4:2
When there were nations in the Bible who were bringing judgment upon themselves because of their sin, God always looked for someone to stand in the gap so He would not have to judge the people.
So I sought for a man among them who would make a wall, and stand in the gap before Me on behalf of the land, that I should not destroy it; but I found no one.
- Ezekiel 22:30
Therefore He said that He would destroy them, Had not Moses His chosen one stood before Him in the breach, To turn away His wrath, lest He destroy them.
- Psalm 106:23
Now some might take this too far and say that God never judges, but we cannot exclude one truth in favor of another. In the Bible we do see instances where God said that not even Moses could have stopped His judgment.
Then the LORD said to me, "Even if Moses and Samuel stood before Me, My mind would not be favorable toward this people. Cast them out of My sight, and let them go forth.
- Jeremiah 15:1
And in these days prophets came from Jerusalem to Antioch. Then one of them, named Agabus, stood up and showed by the Spirit that there was going to be a great famine throughout all the world, which also happened in the days of Claudius Caesar.
- Acts 11:27-28
We also know that Jesus prophesied the destruction of Jerusalem that would happen in year 70 A.D. When giving this prophecy, He did not urge people to pray that it would not happen. For some reason this was something that could not be changed.
THE PROPHETIC IN THE NEW TESTAMENT
IS ALSO ABOUT BRINGING WARNINGS
Some have the idea that the prophetic today is only about encouragement and comfort, but this is not what the Bible teaches.
When we read in the book of Acts, we see that through several prophetic words Paul gets warned about trouble waiting for Him in Jerusalem (Acts 20:22-23 + 21:4,10-11). And as we have already seen in Acts 11:27-28, through a word of prophecy Agabus brought a warning about a famine that was coming.
Think about it, why would not a good God seek to warn people if there was destruction on its way? It's because God is good that He brings warnings about trouble so we will have the possibility to prepare ourselves.
A lot of the New Testament epistles contain warnings about the last days. Even if you hold on to the belief that much of the Book of Revelation is pointing to the destruction of Jerusalem in year 70 AD, you can't claim that the whole book was fulfilled by the destruction of Jerusalem.
I'm not saying that prophecy in the New Testament is mainly about warnings, but we can't totally exclude all prophetic warnings just because we want to be positive.
WHY GOD DOESN'T LIKE ANGRY PROPHETS
First of all we have to make a distinction when it comes to anger. Anger is not always a negative and sinful thing because even Jesus got angry and yet He never sinned. So there is room for anger but it is not a sinful anger; it's holy.
In Ephesians it also talks about being angry but not letting the sun go down on your anger (Ephesians 4:26). Therefore, just getting angry is not a sin; it's how you handle your anger that can make it sinful. The reason I mention this is because we should not condemn someone just because they feel anger arise when they look at injustice.
If we are in tune with the heart of God, we should get provoked when we hear about human trafficking, child abuse, pedophilia, unborn babies being killed and so on. However, this anger should not produce hatred towards other people, but rather a burning compassion which can make us speak stern warnings in an attempt to make people turn from their wicked ways.
It's like a loving father warning his children about the consequences of their wrong decisions. Even though the father's warnings can sound very stern to a child at the moment of delivery, they are motivated by love and not by hatred. The father has no pleasure in bringing the warnings, but he knows it's his responsibility to teach and discipline the child; and he knows that if the child receives the warnings, they will lead to a good life.
Today there are many who almost seem to get a kick out of bringing judgment, which is not the heart of God. When God send prophetic warning they are always motivated by love and bring with them an element of hope - this is why God don't like angry prophets. Still, we cannot ignore the fact that sometimes God sends prophets with a message of warnings.
Sodom did not get any warnings. I believe God had already made up His mind, so He just sent in His angels to bring out the righteous and He informed His friend Abraham about what was going to happen.
When God brings warnings it's because there is a message of hope in it. His warnings can be stern but they are always motivated by love. When a prophetic warning is motivated by hatred, I believe it will corrupt the message because it is not only wrong, but also sinful and does not reflect the heart of God.
Today, I believe, there are both good and bad things going on at the same time; and we cannot always distinguish a message only on the basis of the content. We need to check the fruits and the heart behind it.
I think we should be careful and not just dismiss every prophetic warning as wrong just because it's not positive. At the same time we need to remember that when God brings a warning it's because He wants people to repent.
