There are times when we suffer innocently at other people’s hands. When that occurs, we are victims of injustice. But that injustice happens on a horizontal plane. No one ever suffers injustice on the vertical plane. That is, no one ever suffers unjustly in terms of his or her relationship with God. As long as we bear the guilt of sin, we cannot protest that God is unjust in allowing us to suffer.
