Bodily Fluids & Skin Diseases: How is Deuteronomy relevant to you?

Bodily Fluids & Skin Diseases: How is Deuteronomy relevant to you?

Devotional time in Deuteronomy is not a staple in most Christians’ devo diets. But perhaps that should change. A professor in seminary recommended Deuteronomy be the first OT book we preach when taking a pastorate at a new church. He said the entire gospel of God’s grand redemptive plan resides in Deuteronomy in germinating form. Call me myopic, but I didn’t see it. I couldn’t get past the minutia of Mosaic legislation, all of which seemed redundant in light of Christ’s fulfillment of the Law.

Even more formidable was the challenge of preaching on certain verses without blushing.

Moses, as relevant as ever.

There is a surprising amount of airtime given to bodily fluids, embarrassing diseases, and exactly what to with excrement. But I figured that I would never digest on this chewy book unless I committed to passage by passage peristalsis.

After biting off the challenge, it was a case of chew or choke. I soon learned to mesh in my understanding these two, seemingly contradictory truths:

1. Since all Scripture is profitable for doctrine, correction, and instruction, the book does apply to me as a Christian. 

2. Since Jesus fulfilled the Law, it is no longer binding on me as a Christian.

What that means is that none of the Laws in Deuteronomy are binding on the NT believer, and so I must not try to obey them all, nor should I expect others to obey them.

In practice this means I can’t tell a teenager that Lev 19:28 forbids them to get a tattoo. I also don’t  have to stone naughty kids for rebellion. I you may be thinking: “None. Really? What about Thou shalt not murder?” Here’s the key: the reason I as a believer may not kill, is not because Deut 5:17 tells me that, but because the injunction was given to me by Jesus in the NT.

If I tell my child to obey me because of Deut 5:16, they could respond if they were theologically astute enough (and cheeky enough): “Dad, why is that verse binding on me, but not Deut 14:10, the verse about eating shellfish?” And they’d be right.

(Footnote: I do not subscribe to the arbitrary splicing up of the Law into ceremonial, civil, and moral. This is not taught in Scripture. The Jews saw all the Law as moral. Every point was binding, and the Christ’s life and death did not fulfill only the civil and ceremonial parts, He fulfilled the whole Law).

So why must my child obey me? Because Ephesians 6:1 tells them to. And that is in the NT. Yes, it’s based on the OT principle, as much of the NT is. But though Deut 5:16 is not binding, Eph 6:1 is. Sorry kid; now go take out the trash.

We aren’t surprised many laws of the OT Law are repeated in the NT. The NT regulations will all be consistent with the nature of God and his Laws in the OT. The only laws that are not repeated, are those that were specific to the nation of Israel and their dispensation.

Hence, I can enjoy lobster soufflé, and bearded vulture burger if I so choose. And I can cut my hair any way  my wife likes. And I get to wear blended materials, like polyester (not an enviable privilege, but at least I have the choice). The Jews could not do this. Why? Because the Law was binding on them. For me it is no longer binding, but it does apply.

So when you study Deuteronomy, remember that it is not about keeping rules or breaking rules.

You are learning about God from the commands he gave Israel. And you are applying them to your relationship with him.

I hope this makes some sort of sense.
