Light

This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.

— 1 John 1:5
And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
— John 3:19

There are three kinds of punishment: first, mere retribution, which, since entirely human and not divine, is of evil; second, that which works repentance; and third, that which refines and purifies, working for holiness. But the punishment that falls on whom the Lord loveth because they have repented is a very different thing from the punishment on those who hold fast to their sins. There are also various ways in which the word forgive can be used. A man might say to his son, “My boy, I forgive you. You did not know what you were doing.” Or he might say, “I forgive you; but I must punish you, for you have done the same thing several times, and I must make you remember.” Or again, he might say, “I am seriously angry with you. I cannot forgive you. I must punish you severely, I cannot pass it by.” Or, once more, “Except you alter your ways entirely, I shall have nothing more to do with you. Never, never, till I see a greater difference in you than I dare hope to see in this world, will I forgive you. I would die to save you, but I cannot forgive you. There is nothing in you now on which to rest forgiveness. To say, I forgive you, would be to say, Do anything you like; I do not care what you do.” So God may forgive and punish; and he may punish and not forgive, that he may rescue. To forgive the sin against the holy spirit would be to damn the universe to the pit of lies, to render it impossible for the man so forgiven ever to be saved. He cannot forgive the man who will not come to the light because his deeds are evil. Against that man his fatherly heart is moved with indignation
