Our world prides itself on knowledge. There are people who study every conceivable topic from what celebrities wear and eat, to how many stars are in the sky, and so on. Every one of us has specialized knowledge and interest in a particular subject. For some it’s geography. For others it’s chemistry, biology or sports trivia. The most important kind of knowledge, however, has nothing to do with anything on this earth, but is spiritual in nature. Our society today is sadly lacking in this kind of wisdom. We see this with the increased acceptance of abortion, homosexuality, divorce, and drug and alcohol abuse, as well as the bad behavior of politicians and celebrities of various kinds. The church world too seems to ignore spiritual, moral knowledge, as was evident already in the Old Testament. “Hear the word of the Lord, ye children of Israel: for the Lord hath a controversy with the inhabitants of the land, because there is no truth, nor mercy, nor knowledge of God in the land…My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children” (Hosea 4:1,6). How did this lack of spiritual knowledge show itself? Hosea 4:2 talks about the “swearing, lying, and killing” that went on in the land of Israel, but it was more than that. Parents weren’t bringing their children to the temple to worship God. These children, in turn, showed no interest of spiritual things and knew more about the surrounding nations and the rituals of their idol gods than they did about the worship of Jehovah. Because of this He has was going to “forget their children”, that is, He was not going to save them, because they like their parents weren’t walking in His ways and laws. There were those in Hosea’s day who didn’t read and study what was available of God’s word then. What about us? Do we know more about what Justin Bieber is doing with his life, and what he believes, or are we more aware of what God’s law requires of us? Do we know all the latest hockey or basketball scores, but have trouble quoting the ten commandments? If spiritual things are not a priority, we should make whatever changes we need to so that we can study these things. Being “destroyed for lack of knowledge” is an awful thing. How do we prevent this from happening to us? First of all, we attend church faithfully. Going to church and hearing solid preaching is like having breakfast in the morning. It gets our day and week off to a good spiritual start and fills us with God’s word. Secondly, we attend a Bible study geared for people our age. Although preaching is the chief means of grace, a Bible study allows us to think of God’s word in different and biblical ways that we have never thought of before. It allows us to learn from each other. Thirdly, reading good, theologically sound books and magazines helps us expand our knowledge of church history and doctrine. Finally, having personal devotions is another asset for us spiritually. Although it is good for us to gather with our families around the supper table, praying and reading God’s word by ourselves allows to think through what we are being told in the Bible. All of these are means that God uses to help us grow in such an understanding of His word that we can “be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear” (1 Peter 3:15). By doing this it will also help us when we encounter groups such as the Jehovah’s Witnesses, Mormons, and Seventh-Day Adventists that go door to door trying convert people and leading them down a spiritually wrong path. When we “feed on His word” as the hymn “Take time to be Holy” puts it, then we will be blessed of God and not be destroyed for lack of knowledge, and be kept alive spiritually because of His knowledge in our hearts.
