In an unethical selling technique called the bait-and-switch method, a retailer lures customers into his store by advertising a well-known product at a very low price. When the buyer asks to purchase it, however, he is told that it is out of stock. The salesperson then tries to sell him an inferior line of merchandise, hoping to pocket a bigger profit. The brand name was used just to get potential customers to step inside.

In a similar way, a false teacher uses biblical words to capture interest and gain a hearing. He may talk about Christ, redemption, the cross, and the resurrection, but these "trusted terms" amount to nothing more than a come-on. The "seller" uses them to advertise truths that, as far as he is concerned, are "out of stock." When an interested person responds, he is confronted by beliefs that are completely contrary to God's Word.

Never swallow someone's line just because he uses terms of the Christian faith. Ask the Holy Spirit to help you discern whether or not the speaker is really being true to the Bible. Then you won't get hooked by false teachers who use the doctrinal bait-and-switch method to deceive their hearers.  — Mart De Haan
