The Old Testament lies worlds away from the modern reader, and its wrathful God seems even farther. Crossing from the Old Testament to the New often results in a feeling of unease because of this difference. How can the God that locked mankind out of paradise and destroyed cities be the same God who loved the world so much that He sacrificed His son for our everlasting salvation?

These two versions of God certainly seem incompatible to the secular world. Consider this quote from outspoken atheist, Richard Dawkins.

"The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully."

These words may be harsh, but God, in the Old Testament, did destroy cities. He did destroyed entire peoples. He destroyed babies and children. This is a far cry from the ministry of Jesus, who loved and served the same enemies that the Old Testament God might have destroyed, who healed and comforted, and gently taught, where the Old Testament God might have brought down pillars of flame.

The writer of Hebrews 13:8 declares that “Jesus Christ is the same yesterday and today and forever.” Clearly, this verse tells us that we cannot simply forget the Old Testament. So what, then, are we to think? Can we reconcile these two opposing aspects of God?

Yes—we can. But first, we have to make three realizations.

God Wants the Best for Us                   

Consider your parents. There were times, when you were a child, that they punished you, and they did so not because they were megalomaniacal, not because they were sadistic or bullies, but because they wanted the best for you—because they loved you.

Consider the doctor who, upon seeing an injured limb that threatens the life of the patient, amputates that limb. It is a terrible option—yes. But it is the only option.

These considerations give us a glimpse of God’s mind. The Old Testament is all about God’s plan to use Israel to bless the entire world, to bring His Word to everyone through their prophets and missionaries—they were to be the nation that pointed all others toward God. This was an important mission—the very fate of the world depended upon it.

"The very nature of mankind is to be with its creator."

Scripture states God’s love for His creations over and over. The very nature of mankind is to be with its creator. Each man and woman feels it in their very bones, whether they attribute that longing to God or not.

When we sin and stray from God, we separate ourselves from Him. And on death, that separation is permanent and acutely painful for all eternity—because that’s what Hell really is, separation from God.

He doesn’t want that for any of us.

But God doesn’t directly control mankind. He doesn’t want automatons. So he guides, like the example of the shepherd and his sheep that appears and reappears throughout the Bible.

And sometimes, as we’re about to see, that guidance takes on the form of wrath.

Wrath and Mercy are One

The very idea of the God of the Old and New Testaments being different from one another comes from a critical misunderstanding of what God’s wrath really is.

God’s wrath is God’s mercy. It is love, believe it or not.

God only goes to war when necessary—there is “A time for war and a time for peace,” as Ecclesiastes 3:8 says. Although God punishes evil, He would rather all repent, and He has “no pleasure in the death of the wicked,” as Ezekiel 33:11 says.

Sounds pretty New Testament, doesn’t it?

When God’s wrath does come down, it is, as we’ve learned, like the surgeon’s scalpel, cutting away the disease before it can spread—only instead of bacteria or viruses, the nature of this disease is sin, and its effect is worse than death. If Israel had been destroyed, if the one bulwark against sin and disbelief had been taken down, the message of Christianity might not have made it out into the world, dooming everyone, everywhere.

So God, in His mercy, poured out His wrath, allowing things to happen throughout the Old Testament that we now have a hard time understanding, but that were necessary, nonetheless, to stop this doom.

But believe this—God mourned over every lost life in the way that only a parent can.

The Context Has Changed, Not God

Today, the world seems much different from that of the fire-and-brimstone, plague-filled Old Testament. But it isn’t God that has changed.
