"'Oh, that I might have my request, that God would grant what I hope for, that God would be willing to crush me, to let loose his hand and cut off my life!'" NIV translation
Job continues to describe his frustration as he repeats the fact that he wishes that God would call him home. Have you ever been so physically tired that you just did not want to go on anymore? That is similar to what Job is describing here as he has reached the limits of his physical, mental, and spiritual abilities. He found no help or comfort from his friend and is ready for life to just be over.
"'Then, I would still have this consolation - my joy in unrelenting pain - that I had not denied the words of the Holy One.'" NIV translation
Even in his suffering, Job is still concerned about his relationship with God. We see that a reason that he wants his life to be over is so that he will not dishonor God. He knows that he has reached his limits and is concerned that his faith might break. We can imagine how the devil must have cringed as Job spoke these words.
"'What strength do I have, that I should still hope? What prospects, that I should be patient? Do I have the strength of stone? Is my flesh bronze? Do I have any power to help myself, now that success has been driven from me?'" NIV translation
Job realizes that he is at the end of his rope and that there is nothing that he can do as he faces this "punishment from God". We are reminded of the fact that he is feeling so hopeless because he has the misconception that he is being punished by God. The same thing can happen in our lives as Christians if we forget that Jesus took ALL of our punishment upon Himself. He not only paid the price for our previous sins but He also paid for all of our future sins at the same time. Many times the devil will play with our minds and use people around us to try to get us to forget or even doubt that fact. We must remember that our hope was purchased by the blood of Jesus Christ.
