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.
Honest scientists are increasingly learning truths once deemed unimaginable by those who did not know the scriptures. Some of these truths concern the inner workings of man's mind and body. These relatively recent discoveries reveal that the body emits signals exposing truths intended by men to remain concealed. Sometimes the individual even lies attempting to conceal the facts further. For this reason, people began studying body language in hopes of determining if an individual's movements reveal otherwise hidden truths. Yet, the Bible has included these secrets long before man's scientific discoveries. In fact, the main character found in the oldest book of the Bible understood these principles. Job claimed that the truthfulness of his statements could be seen by simply looking at him. People have long assumed that the conscience is responsible for body language and the scriptures support this claim. Romans 9:1 confirms this truth as Paul stated, “I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost.” The Bible repeatedly shows that the conscience reveals the truth even when man intentionally tries to hide it, lie, or deceive.
