The book of Hebrews was possibly written prior to the destruction of Jerusalem when Nero was persecuting the Christians. Because of the persecution, some Jewish converts were tempted to revert to Judaism, therefore, the book’s author (possibly Barnabas or Apollos) wrote to encourage the Jewish believers to remain strong in their faith in Christ.

Throughout the book, the author emphasizes the superiority of Christ to the ancient prophets, angels, Moses, as well as the priests and Old Testament sacrifices. He added that Christ was the full and final revelation of God and that all the Old Testament prophecies and promises were fulfilled in Him. Therefore, the author warns them that there is no returning to the previous Old Testament sacrificial system for the atonement of sins since it had been superseded by the death, resurrection, and ascension of Jesus Christ.

During his discussion on the priesthood of Jesus Christ, the author makes an interesting statement at the end of chapter five. He states that there was much more he wanted to say about this, but he couldn’t because they would not understand it. He said that they were “dull of hearing” (Heb. 5:11 ESV). The word dull means lazy, sluggish, or listless. Other translations say, “because you no longer try to understand” (NIV), or “you are spiritually dull and don’t seem to listen” (NLT). In other words, they were not putting forth much effort to grow spiritually or learn to discern the voice of God.

 Consequently, when they should be mentoring others, they themselves were still children requiring spiritual milk (Heb. 5:12) and were unskilled, i.e., without experience, or ignorant in discerning the word of God (Heb. 5:13). The author adds that a mature believer can distinguish between good and evil because they have trained themselves by constant use of the Word of God (Heb. 5:14). They make it a habit of listening to the voice of God and putting His Word into practice in their lives.

The picture that comes to my mind as a way of illustrating the two is a child playing with a dull wooden sword compared to a skilled soldier welding a sharp saber. The child will wildly flail the sword around as if he knew what he was doing, but even if he should strike a blow, it would do little harm because the blade is dull. He is unskilled and ineffective. The soldier, on the other hand, has trained himself by constantly practicing the fine art of swordsmanship until he is able to wield the sword skillfully. Also, he has taken the time to sharpen his blade so he can easily wound his opponent. He is skilled and effective because of his constant training and use. The question we each need to ask ourselves then is “Which one am I?” You see, learning to discern good from evil, learning to hear God’s voice clearly, and growing spiritually in the things of God does not happen automatically. We cannot allow ourselves to be lazy, but we must discipline ourselves and develop spiritual habits that will train us to use our “swords” (the Word of God) effectively. I would suggest the following: 1) Develop a daily habit to read the Word of God. But don’t just read it. Get into the habit of asking God to speak to you through the passage you are reading. Listen for His voice and write down in a notebook what He is revealing to you. 2) Then, put what God said to you into practice right away. This is how we “sharpen our blade”. Learning how to pray, prophecy, and be sensitive to the prompting of the Holy Spirit requires practice so ask the Holy Spirit for guidance and strength to do what the Lord is directing you to do. And 3) Teach others. The author of Hebrews chastised the believers because they were not spiritually mature yet to mentor someone else. This is what we all should be doing (Matt. 28:19-20) however, few of us are obeying that commandment. I would encourage you to ask God to show you someone whom you can help as they learn to develop their own spiritual habits and become skilled soldiers with sharpened blades.
