Proverbs 21 contrasts the substance of a wise man versus the substance of a fool. In the home of the wise man, one can find oil and desired treasures. Whenever a need arises, he is prepared to take care of it himself. This is not true of the fool. He cannot take care of himself. We do not know if the fool at some point had treasures and oil as well, but because of his wasteful spending habits, he no longer has those things. In addition to the fool no longer having his substance, he also cannot likely account for how he used those things. Maybe the fool, like far too many Christians, wasted his substance on pleasurable living (Proverbs 21:17). For whatever reason, the fool cannot hold onto the goods entrusted to him by the Lord. Society today has grown accustomed to living on borrowed money, thus spending the future today.
We have already learned that our joy is to be found in the Lord and this joy is a special gift from above. With this truth foundational to our study, what are some things that we can do as believers that will bring us lasting joy? Far too many people think joy surfaces once the stresses of life cease or at least begin to diminish. Yet, the Bible teaches that joy can be found only in faithfully serving the Lord. Today's verse reveals that the disciples found joy through what God had done in and through them! Considering a few more scriptural examples of joy should help to solidify our mindset concerning this subject. The Bible records great joy as the people of God willingly sacrificed to the Lord (1 Chronicles 29:17). Proverbs 21:15 reveals that “It is joy to the just to do judgment.” The book of Luke tells us that there is joy in heaven when one sinner repents (Luke 15:7). From these and other examples, we know that true joy will be found when we willingly serve the Lord God, but never in the things of this world.
