We love to talk about God’s love, mercy, and grace. And while these divine characteristics are essential to understanding His nature and bring us great comfort, they can also paint a rather one-dimensional image of God. An overemphasis of these positive aspects of God’s character can cause us to downplay His righteous anger and just judgment. This is one of the reasons so many people find such a disparity between the Old and New Testaments. They see conflicting images of God portrayed and choose the kind and compassionate God of the New Testament over the harsh and seemingly heartless God of the Old Testament.

But there is only one God, and He is unchanging in His nature. Yes, we may prefer to dwell on His more loving and father-like characteristics, but that does not mean He is incapable of displaying anger or dispensing harsh justice when necessary. And while the Old Testament is the primary place where this darker side of God’s character is displayed, it does not mean He has mellowed with time. Here are just a few reminders of God’s unchanging nature.

“For I the Lord do not change…” – Malachi 3:6 ESV

Of old you laid the foundation of the earth,
    and the heavens are the work of your hands.
They will perish, but you will remain;
    they will all wear out like a garment.
You will change them like a robe, and they will pass away,
    but you are the same, and your years have no end. – Psalm 102:25-27 ESV

And there countless passages in both the Old and New Testaments that reveal the righteous indignation of God.

“I, the LORD, will punish the world for its evil and the wicked for their sin. I will crush the arrogance of the proud and humble the pride of the mighty.” – Isaiah 13:11 NLT

In the greatness of your majesty you overthrow your adversaries;
    you send out your fury; it consumes them like stubble. – Exodus 15:7 ESV

“Now I will soon pour out my wrath upon you, and spend my anger against you, and judge you according to your ways, and I will punish you for all your abominations. ⁹ And my eye will not spare, nor will I have pity. I will punish you according to your ways, while your abominations are in your midst. Then you will know that I am the Lord, who strikes.” – Ezekiel 7:8-9 ESV

But when he [Jesus] saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come?” – Matthew 3:7 ESV

But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed. – Romans 2:5 ESV

And in this portion of the song given by God to Moses, the anger of God is clearly revealed.

“They have made me jealous…” – vs. 21

“…they have provoked me to anger.” – vs. 21

“…a fire is kindled by my anger…” – vs. 22

“…I will heap disasters upon them…” – vs. 23

“I will spend my arrows on them…” – vs. 23

“I will send the teeth of beasts against them…” – vs. 24

Not exactly the kind of sentiments you might find on a Hallmark card. These are clear expressions of God’s anger against the people of Israel and the tangible means by which He intends to manifest His indignation. He even goes so far as to say that He would have completely “cut them to pieces” and wiped them “from human memory” (Deuteronomy 32:26 ESV), but He knew their enemies would have taken credit for it.

God knew that, if He completely destroyed His people, their enemies would arrogantly assume that they were the ones responsible for Israel’s demise.

“Our hand is triumphant,
    it was not the Lord who did all this.” – Deuteronomy 32:27 ESV

And God hates the prideful and arrogant as much as He does the unfaithful and spiritually adulterous. He was not about to give the pagan nations the pleasure of taking credit for something He had done. They were simply instruments in His hands, doing His bidding and acting as His servants. Neither Babylon or Assyria, whom God would use to punish His rebellious people, could take credit for their success. God would raise them up and use them to accomplish His divine will by meting out His just and righteous judgment against His chosen people.

And God points out that His anger was brought on by the actions of those whom He had redeemed and rescued from slavery. His own adopted children had spurned His love and thrown His mercy and grace back in His face through their unfaithfulness.

They stirred him to jealousy… – vs. 16

They sacrificed to demon… – vs. 16

You were unmindful of the Rock that bore you… – vs. 19

…and you forgot the God who gave you birth. – vs. 19

And God makes His damning assessment of His rebellious people.

“…they are a perverse generation,
    children in whom is no faithfulness.” – Deuteronomy 32:20 ESV

What God describes here is serial apostasy. This is not a case of the occasional failure to remain faithful, but of the habitual and willful refusal to follow God’s will. This song is revealing what will become Israel’s because of Israel’s faithlessness.

God will spurn them and hide His face from them. Why? Because that is exactly how they will treat Him. They will turn their backs on Him, choosing instead to worship false gods and demons. They will hide from Him, attempting to disguise their spiritual infidelity and mask their apostasy by feigning faithful adherence to His laws. And so, God will give them a taste of their own medicine. But when God hides His face, the consequences are devastating. When He spurns them, they will experience a form of loss they could have never imagined or anticipated.

God warns of disasters, hunger, plagues, and pestilence. He describes suffering caused by “the teeth of beasts” and “the venom of things that crawl in the dust” (Deuteronomy 32:24 ESV). He foretells of death brought on by the sword and arrows. And no one will be spared. Young men and women will suffer. The nursing child and the old man with gray hair will each endure the same fate. There will be no mercy shown and no grace given.

And while we might not like this image of God, we cannot assume it is somehow incorrect or inconsistent with His character. He is God. And He is fully righteous. All that He does is right, just, and good. In fact, the opening stanza of this poem declared the justice of God.

“The Rock, his work is perfect,
    for all his ways are justice.
A God of faithfulness and without iniquity,
    just and upright is he.” – Deuteronomy 32:4 ESV

He is not the one we should judge. He does not deserve our criticism and, most certainly, does not merit our disdain.

“They have dealt corruptly with him;
    they are no longer his children because they are blemished;
    they are a crooked and twisted generation.” – Deuteronomy 32:5 ESV

God had poured out His love, mercy, and grace upon the people of Israel. He had redeemed and rescued them from captivity in Egypt. He had led them across the wilderness and put up with their repeated displays of ingratitude and constant bickering and complaining. He had brought them to the border of the land of promise and watched as they stubbornly refused to enter in because they didn’t believe He would see them through.

And now, as the next generation stood at the very same border, preparing to enter into the land under the leadership of Joshua, God was informing them that their unfaithfulness would continue. They would conquer the land, but would never enjoy victory over their own apostasy. They would experience the power and presence of God, but would constantly turn their back on Him, seeking instead to give their affections to and place their hopes in false gods.

But God had long ago warned them about what He would do if they proved unfaithful.

“You must not bow down to them or worship them, for I, the LORD your God, am a jealous God who will not tolerate your affection for any other gods. I lay the sins of the parents upon their children; the entire family is affected—even children in the third and fourth generations of those who reject me. But I lavish unfailing love for a thousand generations on those who love me and obey my commands.” – Exodus 20:5-6 NLT

We might not like reading about God’s anger. We may find His judgment difficult to understand or justify. But it is the righteous judgment of God that makes the grace and mercy of God so meaningful. The fact that God would spare a remnant of the people of Israel so He could send His Son as their Messiah shows us just how loving He really is. If we do not understand how just God is in judging those who reject Him and rebel against Him, we will never fully appreciate the value of the mercy and grace He offers. God has chosen to provide justification in place of judgment. He has made a way for sinful men and women to enjoy exoneration rather than condemnation. He has made a way possible for those dead in their trespasses and sins to experience forgiveness and eternal life. And it was all made possible through the death, burial, and resurrection of His Son.

But God showed his great love for us by sending Christ to die for us while we were still sinners. – Romans 5:8 NLT

It is not until we fully understand the justice of God’s wrath that we will fully appreciate the joy of God’s love.
