(Proverbs 14:7 KJV) Go from the presence of a foolish man, when thou perceivest not in him the lips of knowledge.
Whom do you like to spend time with? Why? What kind of companionship do you seek out? Too often we like to hang around with the buddy that acts like a “foolish man” (fool NASB) (3684). They may act stupid, but they are fun. In small amounts that may not hurt us. When it becomes our default behavior we cease growing spiritually and intellectually. We cannot “perceive” (discern NASB) (3045) [yada] “knowledge” (1847) when we are around people who change our focus and make us less willing to think.
Something else to think about: What kind of an influence are we? Do we attract others because we are caustic and deprecating? Do we run a Saturday Night Live monologue about the profane all the time? Do we keep others from discerning the things of God?
So? Don’t drown your sense of humor. Don’t act like you don’t know anything about the popular culture. Be aware. Find people who stimulate your sense of the eternal. Become such a person.
