Pain is always painful, but there is a great deal of redemptive value in it when we can cooperate with the hand of God. The author does a good job of encouraging a proper response to His hand. In the turmoil of fear and doubt that accompany spiritual pain, pain that is not related to the consequence of sin, there is a need to maintain a proper attitude toward God. In the proper heart, our heavenly Father is able to recreate our human nature into the heart of Jesus.
We all have to walk a similar road, but only a few embrace the pain long enough to be recreated in His image. There are always an adequate supply of nearby outspoken 'voices' that desire to find a solution. Out of misunderstanding, these voices often assume that the discipline we experience is of punishment rather than the discipline that shapes our lives.
If it appears that God's blessing is far from you and others around you are attributing your 'failure' to some sin in your life, it may be that God is testing your soul in the crucible of pain and perplexity to prepare you for promotion.
This book is a must read volume on the subject of righteous suffering. Read it. It is like an ointment that soothes your soul. It brings focus to the purpose of difficulty and pain in our lives. It helps Jesus bring forth a newness of life from the depths of your pain. Like a mother who brings forth a child, this pain is soon forgotten once its work is done.
