Then there is another point to be noted, viz. we must not import into that word 'vengeance,' when it is applied to divine actions, the notions which cluster round it when it is applied to ours. For in its ordinary use it means retaliation, inflicted at the bidding of personal enmity or passion. But there are no turbid elements of that sort in God. His retribution is a great deal more analogous to the unimpassioned, impersonal action of public law than it is to the 'wild justice of revenge.' When we speak of His 'vengeance' we simply mean—unless we have dropped into a degrading superstition—the just recompense of reward which divinely dogs all sin. There is one saying in Scripture which puts the whole matter in its true light, 'Vengeance is Mine; I will repay,' saith the Lord; the last clause of which interprets the first. So, then, with these elucidations, we may perhaps see a little more clearly the sequence of the Psalmist's thought here—God's forgiveness, and co-existing with that, God's scourging of the sin which He forgives; and both His forgiveness and the scourging, the efflux and the manifestation of the divine holiness. Now just let us look at these thoughts. Here we have—

I. The adoring contemplation of the divine forgiveness.

I suppose that is almost exclusively a thought due to the historical revelation, through the ages, to Israel, crowned, as well as deepened, by the culmination and perfecting of the eternal revelation of God in Jesus Christ our Lord. I suppose the conception of a forgiving God is the product of the Old and of the New Testament. But familiar as the word is to us, and although the thing that it means is embodied in the creed of Christendom, 'I believe … in the forgiveness of sins,' I think that a great many of us would be somewhat put to it, if we were called upon to tell definitely and clearly what we mean when we speak of the forgiveness of sins. Many of us, prior to thinking about the matter, would answer 'the non-infliction or remission of penalty.' And I am far from denying that that is an element in forgiveness, although it is the lowest and the most external, in both the Old Testament and the New Testament conception of it. But we must rise a great deal higher than that. We are entitled, by our Lord's teaching, to parallel God's forgiveness and man's forgiveness; and so perhaps the best way to understand the perfect type of forgiveness is to look at the imperfect types which we see round us. What, then, do we mean by human forgiveness? It is seen in multitudes of cases where there is no question at all of penalty. Two men get alienated from one another. One of them does something which the other thinks is a sin against friendship or loyalty, and he who is sinned against says, 'I forgive you.' That does not mean that he does not inflict a penalty, because there is no penalty in question. Forgiveness is not a matter of conduct, then, primarily, but it is a matter of disposition, of attitude, or, to put it into a shorter word, it is a matter of the heart; and even on the lower level of the human type, we see that remission of penalty may be a part, sometimes is and sometimes is not, but is always the smallest part of it, and a derivative and secondary result of something that went before. An unconscious recognition of this attitude of mind and heart, as being the essential thing in forgiveness, brings about an instance of the process by which two words that originally mean substantially the same thing come to acquire each its special shade of meaning. What I refer to is this—when a judicial sentence on a criminal is remitted, we never hear any one speak about the criminal being 'forgiven.' We keep the word 'pardon,' in our daily conventional intercourse, for slight offences or for the judicial remission of a sentence. The king pardons a criminal; you never hear about the king 'forgiving' a criminal. And that, as I take it, is just because people have been groping after the thought that I am trying to bring out, viz. that the remission of penalty is one thing, and purging the heart of all alienation and hatred is another; and that the latter is forgiveness, whilst the former has to be content with being pardon.

The highest type of forgiveness is the paternal. Every one of us who remembers our childhood, and every one of us who has had children of his own, knows what paternal forgiveness is. It is not when you put away the rod that the little face brightens again and the tears cease to flow, but it is when your face clears, and the child knows that there is no cloud between it and the father, or still more the mother, that forgiveness is realised. The immediate effect of our transgressions is that we, as it were, thereby drop a great, black rock into the stream of the divine love, and the channel is barred by our action; and God's forgiveness is when, as was the case in another fashion in the Deluge, the floods rise above the tops of the highest hills; and as the good old hymn that has gone out of fashion nowadays, says, over sins:

'Like the mountains for their size,
The seas of sovereign grace arise.'

When the love of God flows over the black rock, as the incoming tide does over some jagged reef, then, and not merely when the rod is put on the shelf, is forgiveness bestowed and received.

But, as I have said, the remission of penalty is an element in forgiveness. Some people say: 'It is a very dangerous thing, in the interests of Christian truth, to treat that relation of a loving Father as if it expressed all that God is to men.' Quite so; God is King as well as Father. There are analogies, both in paternal and regal government, which help us to understand the divine dealings with us; though, of course, in regard to both we must always remember that the analogies are remote and not to be pressed too far. But even in recognising the fact that an integral part of forgiveness is remission of penalty, we come back, by another path, to the same point, that the essence of forgiveness is the uninterrupted flow of love. Remission of penalty;—yes, by all means. But then the question comes, what is the penalty of sin? And I suppose that the deepest answer to that is, separation from God. But if the true New Testament conception of the penalty of sin is the eternal death which is the result of the rending of a man away from the Source of life, then the remission of the penalty is precisely identical with the uninterrupted flow of the divine love. The mists of autumnal mornings drape the sky in gloom, and turn the blessed sun itself into a lurid ball of fire. Sweep away the mists, and its rays again pour out beneficence. The man who sins, piles up, as it were, a cloud-bank between himself and God, and forgiveness, which is the remission of the penalty, is the sweeping away of the cloud-bank, and the pouring out of sunshine upon a darkened heart. So, brethren! the essence of forgiveness is that God shall love me all the same, though I sin against Him.

But now turn, in the next place, to

II. God's scourging of the sin which He forgives.

Look at the instances in our psalm, 'Moses and Aaron among His priests…. They called upon the Lord and He answered them. Thou wast a God that forgavest them, and Thou tookest vengeance of their doings.' Moses dies on Pisgah, Aaron is stripped of his priestly robes by his brother's hand and left alone amongst the clouds and the eagles, on the solitary summit of the mountain, and yet Moses and Aaron knew themselves forgiven the sins for which they died those lonely deaths. And these are but instances of what is universally true, that the sin which is pardoned is also 'avenged' in the sense of having retribution dealt out to it.
