Now, I know that I am certainly not the smartest or the wisest person on Earth, but I do know a little something about knowing the difference between being smart and being wise. According to Merriam-Webster, a few of the definitions for "smart" are: mentally alert, knowledgeable, shrewd, or intelligent. And one of the definitions for wise is: marked by deep understanding, keen discernment, and a capacity for sound judgment.
With these definitions in mind, I think I'll take the liberty to point out what might be an obvious truth to many: just because you are smart, it does not mean you are wise. To me, being wise means seeing opportunities to apply what you know in certain scenarios to produce a good outcome for yourself and/or for others. So you might be "book smart" as some say, but you are wise when you know how and when to apply what you know. Sometimes, we can gain wisdom from truly listening to those who have experienced what you have yet to experience yourself so we can avoid whatever pitfalls might be there during the experience. Moreover, it's not just about avoiding pitfalls, it's also about finding the greatest level of success. Then there are other times when you just have to experience things first-hand yourself then hopefully, you learn whatever lesson you needed to learn. I can honestly say that I recognize I am smart, but I also see that I need a whole lot more wisdom. I certainly have not "arrived." (Please pray for those who do think they have... I laugh as I write this, but at the same time I am so serious.) The Apostle Paul says in 1 Corinthians 10:12, "...let him that thinketh he standeth take heed lest he fall." ["Lest" means for fear that — often used after an expression denoting fear or apprehension ("let him...take heed [for fear that he might] fall").] To provide a context for that verse of Scripture, Paul was talking about those who did not please God in the wilderness and those who tried to tempt (or test) Christ and failed.
Some people just think they know everything about everything, but they have to be careful because it is inevitable that they will slip up one day. After all, we are fallible humans, right? Those who think they know it all are experiencing pride. Pride can make people do foolish things. I don't stand by my own strength and knowledge, but I stand because Christ, my Rock, holds me up. The fear of (reverence for) God is the beginning of wisdom (Psalm 111:10).
I hope I never lose the ability to tell when I should be applying what I do indeed know. Context always matters. I have to be careful that I don't try to apply what I know at the wrong time and/or for the wrong reason (ex. trying to justify myself or trying to prove a point just to make myself look good). Yes, I do believe I am smart, but I'd be wise to not rely solely on "smarts," but to trust in the Lord Who has allowed me to have opportunities to apply what I have learned from the best Book from which to gain "book smarts," His holy Word, the Bible.
I just want to encourage and inspire as many people as I can for Jesus Christ.
