I’d first like to say, the Bible is 100% true. Based on the evidence, and everything else, and based on the ethics it describes. But, the question is whether we need the Bible, necessarily to know what’s right or wrong. And that’s what I’m dealing with in this. Not whether the Bible is true. Because the Bible is perfectly true.

But, the most solid foundation for morality, is the ethics of Logos. The Bible describes that ethics. But so does Confucius, Mo Tsu, Lao Tsu, Socrates, Maimonides, Plato, Aristotle, Pythagoras… the list goes on.

It’s not the Bible we need to be moral. We already have morality wired into us. It’s in our genetic make up.

But, Secular Ethics—such as Peter Singer—can be wrong. For instance, Peter Singer wants infanticide to be an option up to thirty days after birth. Secular ethics also says that transitioning a child at the age of 5 is not only acceptable, but it’s immoral to oppose such a thing.

Do you understand? Humans are wired to value life, property and God. But, secular ethics not only makes you stop valuing life, it makes you think property is an evil thing, and it makes you blasphemous toward God. As, it says “God’s a moral monster.” While they do the same thing. “Why is it okay for God to have Israel slaughter babies in war?” While they turn around, and try to make it okay to inject Babies with Pentobarbital, or even healthy adults who simply have mental issues.

You see how the roles reversed? It makes God justified, that they hypocritically do the same things. They get mad at God for flooding the world, or detailing the realities of war, while they form legal methods of performing murder on innocent victims.

So, I don’t think the Bible is necessary for a foundation of Morality. I think morality is founded on the Natural Law which governs human nature, and causes flourishing within us. But, for sure, the Bible is a record of that Morality, from the first establishment of Law, to the framework of Christ and the Prophets.

The Bible is very much a history of Morality, from the earliest burgeons of law, to the Universal Ethics found by Christ. Which, the Old Covenant Morality was justified. You infringe on someone else, you do deserve a death penalty. But, that’s what Jesus saves us from. Not so we may continue on sinning, but so we can have a pure conscience, and do good, even though we may have been greatly evil in the past.

No. You don’t follow everything in the Bible.

So, theologically speaking, the Old Testament is the Old Covenant. It’s what used to save you—so to speak. And it’s what’s going to be used to damn you.

So, when Jesus came, the Law changed with His resurrection. It says that in Hebrews that with a change of Priesthood comes a change of law. So, everyone is under the jurisdiction of the Judaic Law. Everyone. Every nation, tribe and people. So, like a Don from Oxford said, if you are enticed to follow a foreign God, you have to kill the person who enticed you. Or, if you work on Sunday, you have to be put to death. Or, you’re a homosexual, you have to be put to death. Jesus even makes it stricter, if you look after a woman, and lust after her, or call your brother “Worthless” you deserve to die, as well.

So, 100% of Paul’s letters, are trying to convince Christians not to follow the Old Testament law. Why? Well, do you remember those guys who just leaned on the Ark and they died? For seemingly no reason? That’s the severity of the Law in the Old Testament. It warrants a death sentence for even touching it, let alone trying to follow it. Because, humanity errs, and is never going to be perfect. So, they fall into the trap of the Law—which condemns every sin.

So, how are we to have life? Well, we have life by forfeiting our sin, including our judgment, and allowing Christ to fill us with His Spirit. We sever ourselves from the Old Covenant, which commands every Nation under the sun, including Israel, to be destroyed. And we are made to follow the New Covenant, prophesied in Jeremiah. That the Law will be written on our hearts.

And the Law is written on our hearts. There’s a natural pattern that people follow, and everyone knows right from wrong at infancy. And they fall away from that, and that’s what ultimately leads to their damnation. Is they’re caught in their sins. So, that sin is what leads to damnation, and that sin is judged by the Old Testament law.

Which, the only one who ever followed the Old Testament law perfectly, that was Jesus. He followed it perfectly, never erring, and the curse of the Law, found in Deuteronomy, was punctured into His hands and feet. He became our curse. So we wouldn’t be cursed by the Law, and could be set free, to follow after Jesus’ yoke. Which is light. Which is a one time sin offering, for all of our sin. And the only thing we have to do, is believe He is Who He says He is, and repent. We don’t even have to follow the Torah anymore.

So what is the Old Testament used for? It’s God’s commandments, which He will use to judge the world. All those sins that require a death sentence, all those verses about horrible things armies do to cities, that’s the judgment that comes down from God. You can read the Prophecies in the Old Testament, that they testify to those things, and speak of the prophetic discipline which God will impose on the disobedient. Which, a lot of those prophecies are scary. So, you don't want to be found erring. Air on the side of caution, and fear God, and follow His Law that Jesus spoke. As, we’re to follow the New Covenant, and the Law given by Christ and His apostles and saints.

So, the Old Testament is a Casebook for God’s judgment, and punishment for the wicked. It’s what guilty sinners need, and written in the book itself, is redemption fro God’s people. That through belief in the LORD, you’ll be redeemed through the Law even, by faith alone. And that’s actually a huge part of the Prophecies in scripture, is the redemption of God’s people through Faith alone.
