In the Old Testament, we find the idea that God enters into the sufferings of His people. "In all their afflictions, He was afflicted." The relation of God to the woes of the world is not that of a mere spectator. The New Testament goes further, and says that God is love. But that is not love which, in the presence of acute suffering, can stand outside and aloof. The doctrine that Christ is the image of the unseen God means that God does not stand outside.
