“if you receive my words.” It is clear throughout Proverbs that people can gain wisdom and the understanding, discernment, discretion, etc., that comes with it. But that takes a concerted effort, as the verses show, and sadly, many people do not make any effort to gain wisdom, and many of them would not even know where to start.
In today’s world, the Adversary has a very aggressive agenda against people gaining wisdom. It is possible to spend hundreds of hours wasting your time and not gaining an ounce of wisdom or understanding. And, considering that in the ancient world “wisdom” and “understanding” did not just refer to the knowledge one had but the practical application of that knowledge—using your knowledge as you lived life, worked, helped others, volunteered, and made a positive contribution to society—spending an inordinate amount of time selfishly engaged in activities that neither enrich the individual or contribute to society is a real “win” for the Devil and a real loss for the individual.
God created people “to do good works” (Eph. 2:10) and if we are not doing them we are defying Him, whether we mean to be or not. “I’m not hurting anyone” sounds good, but it is not God’s will for our lives. A hermit can live his life in a cave and “not hurt anyone.” God created us to help people and make disciples, and we either are or we aren’t. If we aren’t, we are (and will be) the losers.
“store my commandments with you.” The words and commands of God are a great treasure, so the believer is wise to store them up in his mind and keep them with him at all times. The Hebrew is literally, “hide with you,” but that does not make good sense to the modern reader. However, in biblical times people would hide things that were valuable to them because the culture did not offer many safe places to put something. People’s houses and tents were always susceptible to people entering at a time when no one was home and stealing valuables. The commands are to be “with us,” in our minds. God sets Himself as an example in this, and keep the Word with Him, as we see in John 1:1, because the Scripture says “the word was with God.”
