There is a vast amount of information on any subject available to us nowadays. The last two times I got really sick, based upon the symptoms my wife was able to search online and arrive at the right diagnosis each time before my doctors thought of it. YouTube is a popular site that shows just about anything you want to see or hear, but here's the problem of having too much information available to us. Let's just look at the many Catholic videos posted alone. A speaker would present a strong point of view with conviction, then another video will attack him by pointing out all his errors. Or a speaker sounding very Catholic starting out, then gradually he tells us that the Pope is wrong, EWTN has been deceived by Satan, etc. Overall, it's no longer two sides disagreeing; it's everyone thinking that only he knows the truth and everyone else is wrong. Of course, this can definitely cause mass confusion (guess who's happy about all this).
So, what are we to do? Simple ~ ignore all of them. Keep your eyes on Jesus alone and shut out all noises that are distracting and confusing. Be fully occupied with the Lord and let all else go.
