It seems like there’s a pretty standard path to apostasy that some believers follow:
Step 1: “I have an idea about something mysterious or controversial in the gospel.” Not dangerous–this is a natural result of study and reflection, and undoubtedly happens often.
Step 2: “This idea makes sense to me. I find it useful.” Getting a little risky here–it’s so easy to be seduced by our own imagination, hence the ample warnings against such in the scriptures.
Step 3: “Since I find my theory reasonable and attractive, I think that it is true.” Patently fallacious. Reason and attractiveness do not make ideas true; these criteria are arbitrary, not naturally corresponding to fact. Plenty of things could be reasonable and attractive but not true–hence the prophetic warnings against the “philosophies of men.” At this step, one is rapidly approaching apostasy, if not already there.
Step 4: “I will now enlighten the world with my valuable discoveries.” At this point, someone is very likely in a state of apostasy.
The lesson is clear: beware of pride. We must keep a very tight rein on our vain imaginations. This is important for bloggers–including me–to always remember.
