"But examine everything carefully; hold fast to that which is good;"
1 Thessalonians 5:21
Things aren't always what they seem to be. The eagle in the photograph may appear to be real, but it isn't. It's a sculpture. The more familiar you are with a live eagle, the more easily you will discern that the one in the picture is an imitation. In the same way, the more we study the Bible and come to know the true Christ and His gospel, the better equipped we are to identify an imposter. We should never take at face value the teachings of any man or woman, but test them by the scriptures. Always take a closer look.
