None of us wants to be thought of as a simpleton....that "dunce in the corner" with the pointy hat. Yet, many times we are just that: "simple"...in that we believe every word. "The simple believeth every word." Proverbs 14:15
We must put the "words" that come "in" to the test...the standard by which all should be measured: the Bible.
Only then will we be able to discern truth from error...only then can we attain to being wise as serpents. "Behold, I (Jesus) send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves." Matthew 10:16
