If you know me at all, you'll know I'm a Star Trek nut. And one of the coolest things they did on those shows was talk to the computer like it was a person. The voice recognition knew exactly what you said and would do whatever you told it to do.
When Siri first came out on the iPhone, I had high hopes. "My very own Star Trek computer, waiting for my commands!" is what I thought. Turns out it's not like that. Siri is useful, just not Trek-level computing. Yet.
But think about how much voice recognition has improved on computers and smartphones in just the last 10 years. Now I can speak to my computer and dictate, just like I'm doing with this article right now. And most of the time, it's correct.
Jesus says in John 10:27:
"My sheep hear my voice, and I know them, and they follow me."
Lots of things to look at in this verse. First and foremost, we must be a part of the flock. We can't hear our master's voice if we're not in the group to hear it. Secondly, when we're in that flock, Jesus knows us. He knows who we are. He knows what our heart is. And third, if we hear his voice and obey, we will follow him.
Voice Recognition isn't quite up to Star Trek standards yet, but it's getting there. One thing we can always depend on is Jesus' voice - if we hear it, we know we're in the right place.
