Earthly parents sometimes chasten their children according to their own pleasure, but the Lord chastens His children ONLY for their profiting. In addition, earthly parents will sometimes err by disciplining their children for convenience to end the child’s inconvenience brought upon the parent. The end goal turns out to be the satisfaction of the parent rather than the sole good of the child. However, in God’s dealings with His children, He chastens for the benefit of the one receiving the chastening. He uses His chastening to help make His children partakers of His holiness. When they have done wrong, He wants them to repent (Revelation 3:19). When they have gone astray, He wants them to find correction (Job 5:17). God, as a Father, always chooses to do what is best for His children. It is always exclusively for their profit!
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.
