Straight lines look crooked with enough pressure from a crowd. Psychologist Solomon Asch demonstrated this during a landmark experiment in the 1950s. He seated one unsuspecting test subject in a room with numerous actors, and displayed two cards to everyoneโone featuring a solitary straight line, the other displaying three lines of obviously varying lengths with only one matching the line on the first card. The assignment was straightforward: match the lines. So easy, a monkey could do it blindfolded.
Shockingly, over 75% of participants got the answer wrong. How did they fudge such a simple task? Because the actors were instructed to lie and swear that the shorter lines matched the one on the first card although anyone with eyes could see that they absolutely didnโt. Many of the respondents initially matched the lines correctly, but changed their minds due to peer pressure. Dr. Solomon concluded that human beings will do what is wrong even though they know what is rightโall it takes is enough influence from others.
Solomon the Preacher reached a similar conclusion from the experiment of life: spend enough time walking with someone and you will eventually start walking like themโfor better or worse. โHe that walketh with wise men shall be wise,โ he wrote, โbut a companion of fools shall be destroyedโ (Prov. 13:20, KJV). Who you befriend influences what you believe and how you behave. Friendship is formative, which is why you must stick close with companions of character and commitment who draw you closer to Christ and avoid โfriendsโ who lead you astray by making sin easier and obedience harder. You cannot live righteously while walking with the wicked, nor can you live righteously without walking with the righteousโso choose your friends carefully.
When you hang around a fire for a while, smoke will cling to your clothesโwhen you hang around people who are playing with fire by living disobediently, their sin will cling to your life (Prov. 22:24-25). But when you fellowship with believers who are โon fireโ for the Lord with white-hot zeal for His glory, the flame of your own zeal will burn hotter. The best kind of friend is one who improves your sanctification and holiness, not one who hinders it: โIron sharpens iron, and one man sharpens anotherโ (Prov. 27:17). Faithful friends also tell you what you need to hear rather than what you want to hear: โFaithful are the wounds of a friend; profuse are the kisses of an enemyโ (Prov. 27:6; cf. 27:9-10). Christlike companions, furthermore, love you at your worstโnot at your best (Prov. 10:12; 17:9, 17; 19:4, 6-7).
Still, even the best of earthly friends will fail and disappointโthere is only One who will never leave you nor forsake youโthe Friend of sinners: โA man of many companions may come to ruin, but there is a friend who sticks closer than a brotherโ (Prov. 18:24; cf. John 15:13-15; Rom. 5:8). Take an honest inventory right now of your closest friendsโwhere are they taking you and how are they โmakingโ you?
