The special privilege God meant as a tool for witness, they [the Israelite’s] were to be a channel and you know what happened don’t you? Instead of them seeing themselves as a witness, instead of them seeing the difference as a way to reach people, instead of them standing up and saying, I’m different and consequently the world is going to say what’s the difference and I can tell them that God has made me different. Instead of that it became an excuse for carnal, selfish, self-glorification and pride.
It can happen with us too. We’re to be different aren’t we? We’re to be completely different than the rest of the world. We’re to walk a different walk, talk a different talk, think a different way. Read later in Ephesians and you’ll find out we are to walk not as the Gentiles walked, not as the heathen walk in the vanity of their mind. We are to walk in love. We are to walk in light. We are to walk in wisdom. We
are to walk in the spirit. Our conversation, our manner of life, our walk is to be totally different than the rest of the world. And that it is to be different because want them to take note of us. First of all, and secondly, God wants to keep us separated so different that we can’t mingle with them. It’s the same two things again. And hopefully the world will see the difference and we’ll say to them it’s Jesus Christ
that made the difference and here’s how He can make a difference in your life. And that’s exactly what Israel should have done. Instead of doing that, Israel became proud, loved the difference, celebrated the difference, became proud about the difference, and elevated themselves as if they were better than everybody else.
And I hate to think about it, but I think it’s even possible that that’s happening in Christianity or could happen. Where Christianity forms some sort of an elite that think they’re better than everybody else. And instead of really being a channel to reach the world, we become an isolated little group of people with our own little lingo and our own little deal and our own little code and our own little bumper stickers and our own little radio stations and TV stations and our own books and our own everything, and it’s us for, no more, shut the door, you know. ~ John McArthur, teaching on Ephesians 2: 11-12
