“The one who states his case first seems right, until the other comes and examines him” (ESV).

Many people have changed their beliefs because they heard someone make a persuasive case for some other point of view. Slow down. Don’t be so quick to change your beliefs. You need to examine their case more closely. If you can’t find anything wrong with their argument, ask others what they think of it. It’s particularly important that you ask someone who shares your current belief to examine this new point of view to see if they can find fault with the case being made. Or, see if you can find any formal debates on the matter. At the end of the day, you may discover that you were wrong and the other view is true, but more times than not, you’ll find that the case being made is not as strong as you first believed.
