The Bible repeatedly mentions the bitterness of soul (1 Samuel 1:10; Job 3:20; Job 7:11; Job 10:1; Job 21:25; Isaiah 38:15). Job testified to speaking in the bitterness of his soul—weary of his life (Job 10:1). Hannah “was in bitterness of soul” (1 Samuel 1:10) when she spoke to the Lord concerning her desire to birth a son. Interestingly, the Book of Job contains the majority of references to bitterness of soul. It is hard to imagine any mortal man enduring more afflictions of the soul than Job. He was afflicted so deeply, he cursed the day that he was born (Job 3:1). Eventually, his bitterness of soul won out and caused him to sin against the Lord. Hannah, however, spoke to the Lord in bitterness of soul and God rewarded her for her faithfulness.
A good Bible student often incorporates many of the same tactics as a good detective. Defining Bible words involves such a task. No single verse specifically defines the word bitterness. Yet, a careful study of a few verses will help to bring the pieces together and to provide understanding. According to Isaiah, bitterness and peace are at opposite ends of the emotional spectrum (Isaiah 38:17). Proverbs associates the word bitter directly to the word sharp (Proverbs 5:4). And, lastly, the word bitter is connected to the word affliction (2 Kings 14:26, Lamentations 1:4). Using these scriptural clues, a good student will understand bitterness to be a sharp affliction. Additionally, consider the connection between the words bitter and bite, making bitterness a sharp affliction with bite. Bitterness always begins on the inside of an individual and, as we will learn, eventually works its way to the outside for others to see.
No sensible person would ever ask to be on the receiving end of the wrath of God. The thought is completely illogical! Yet, this scenario takes place every day in the lives of those who live with hardened hearts toward the things of God. The Bible affirms that a humble spirit begs God's attention and brings His corresponding blessings (Isaiah 66:2). Contrariwise, a hard heart also garners God's attention but for judgment rather than blessing. Today's passage points out that the hard heart treasures up wrath against itself. This wrath rarely takes place immediately, but it will come in the “day of wrath.” It is important to recall that hardness of heart brought the plagues upon Egypt and it brought blindness to the Jews in Jesus' day. Ultimately, it will bring eternal damnation in the lake of fire to all those who fail to accept God's payment for sin.
Sometimes the most effective means of defining a Bible word involves researching those words commonly associated with the word in question. Delicate is such a word. On four occasions, the Bible associates the word delicate with variations of the word tender (Deuteronomy 28:54, 56; Isaiah 47:1). This association provides the Bible student with the sense that a delicate person is easily broken spiritually. Additional Bible study demonstrates that a tender heart remains pliable and prone to brokenness before the Lord. Conversely, the Bible points to a hardened heart as remaining obstinate. The word obstinate conveys an inflexibleness or stubbornness. As believers, we should aspire to be tenderhearted before the Lord with a heart easily moved to accomplish His will.
