When a man dies, will he come back to life? [If so,] I would wait all the days of my struggle until my relief comes. You would call, and I would answer You. You would long for the work of Your hands.
For then You would count my steps but would not take note of my sin.Job never got to read the New Testament, but his answer came for us to read.Galatians 6:7-8
