“In, but not of” — if you’ve spent much time Christian circles, you’re probably familiar with this slogan. In the world, but not of the world. It captures a truth about Jesus’s followers. There’s a real sense in which we are “in” this world, but not “of” it.

In, but not of. Yes, yes, of course.

But might this punchy phrase be giving the wrong impression about our (co)mission in this world as Christians? The motto could seem to give the drift, We are in this world, alas, but what we really need to do is make sure that we’re not of it.

In this way of configuring things, the starting place is our unfortunate condition of being “in” this world. Sigh. And our mission, it appears, is to not be “of” it. So the force is moving away from the world. “Rats, we’re frustratingly stuck in this ole world, but let’s marshal our best energies to not be of it.” No doubt, it’s an emphasis that’s sometimes needed, but isn’t something essential being downplayed?

We do well to run stuff like this through biblical texts. And on this one in particular, we do well to turn to John 17, where Jesus uses these precise categories of “in the world” and “not of the world.” Let’s look for Jesus’s perspective on this.

Not of This World

On the eve of his crucifixion, Jesus prays to his Father in John 17:14–19,

I have given them your word, and the world has hated them because they are not of the world, just as I am not of the world. I do not ask that you take them out of the world, but that you keep them from the evil one. They are not of the world, just as I am not of the world. Sanctify them in the truth; your word is truth. As you sent me into the world, so I have sent them into the world. And for their sake I consecrate myself, that they also may be sanctified in truth.

“Being ‘not of the world’ isn’t the destination in these verses but the starting place.”

Notice Jesus’s references to his disciples being “not of the world.” Verse 14: “The world has hated them because they are not of the world, just as I am not of the world.” And there it is again in verse 16: “They are not of the world, just as I am not of the world.”

Let’s all agree it’s clear that Jesus does not want his followers to be “of the world.” Amen. He says that he himself is “not of the world,” and his disciples are “not of the world.” Here’s a good impulse in the slogan “in, but not of.”

It’s Going Somewhere

But notice that for Jesus being “not of the world” isn’t the destination in these verses but the starting place. It’s not where things are moving toward, but what they’re moving from. He is not of the world, and he begins by saying that his followers are not of the world. But it’s going somewhere. Jesus is not huddling up the team for another round of kumbaya, but so that we can run the next play and advance the ball down the field.

Enter verse 18: “As you sent me into the world, so I have sent them into the world.” And don’t miss the surprising prayer of verse 15: “I do not ask that you take them out of the world, but that you keep them from the evil one.”

Sent into This World

Jesus is not asking his Father for his disciples to be taken out of the world, but he is praying for them as they are “sent into” the world. He begins with them being “not of the world” and prays for them as they are “sent into” the world.

So maybe it would serve us better — at least in light of John 17 — to revise the popular phrase “in, but not of” in this way: “not of, but sent into.” The beginning place is being “not of the world,” and the movement is toward being “sent into” the world. The accent falls on being sent, with a mission, to the world — not being mainly on a mission to disassociate from this world.

Crucified to the World — and Raised to It

Jesus’s assumption in John 17 is that those who have embraced him, and identified with him, are indeed not of the world. And now his summons is our sending — we are sent into the world on mission for gospel advance through disciplemaking.

Jesus’s true followers have not only been crucified to the world, but also raised to new life and sent back in to free others. We’ve been rescued from the darkness and given the Light not merely to flee the darkness, but to guide our steps as we go back in to rescue others.

So let’s revise the popular phrase “in, but not of.” Christians are not of this world, but sent into it. Not of, but sent into.
