Can God’s word “return void”?

Isaiah 55.11.

So one night I and my friend Jason (not his real name, and you’ll soon see why) were walking from the car to the coffeehouse. Enroute some vagrant asked us for spare change. Jason got it into his head this was a “divine opportunity”: It’s time to proclaim the gospel to this person! It’s time to get him saved.

That’s how we wasted the next 15 minutes. Yep, wasted. Because the vagrant was. Either he was drunk, or off his meds, or had recently suffered a head injury, or otherwise had some condition which made him incoherent. Jason asked him questions to determine whether he understood the gospel… and the guy would start rambling about how he believed men and women should be together. In which context I don’t know. (Hey, this article is about context, so I had to bring it up at some point.)

Jason kinda had this poor guy cornered in a doorway, pressuring him for some sorta confession of faith. Finally, after he extracted something he considered satisfactory, we went and got that coffee. And debated whether the interaction did the poor vagrant any good.

“He’s not gonna remember any of that in the morning,” I commented.

“He will so!” Jason insisted. “That’s the word of God in him now. It won’t return void.”

If you’re not familiar with Christianese you may not understand the “return void“ bit. I once had a pastor try to explain it this way: “It’s like you send someone a check, but they don’t cash it and send it back to you with ‘void’ written on the front of it.” Why anyone would do this, I don’t know. But no, it’s not what the verse means. Here’s the verse:

Isaiah 55.11 KJV

So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.

Here’s what Jason, and plenty of Christians like him, believes: Let’s say we share Jesus with someone, but the someone won’t believe what we tell them, no matter what. Well, take comfort in the fact God’s word—which is what we shared with them, ’cause it’s either based on bible, or contains a whole lot of bible quotes—doesn’t “return void.” It does exactly what it’s meant to, and puts the gospel in ’em. Even though it totally doesn’t appear to, ’cause the person resists it for years, it eventually worms into their soul and does something to ’em. It just does.

Why’s this? ’Cause it’s God’s word. So it’s been infused with supernatural divine power.
