The Scriptures speak of law, of its demands, of its penalty, of sinners as arraigned at the bar of God, of the day of judgment. The question is, How shall man be just with God? The answer to this question determines the whole method of salvation. The question is not, How a man can become holy? but, How can he become just? How can he satisfy the claims which justice has against him? It is obvious that if there is no such attribute as justice in God; if what we call justice is only benevolence, then there is no pertinency in this question. Man is not required to be just in order to be saved. There are no claims of justice to be satisfied. Repentance is all that need be rendered as the condition of restoration to the favour of God. Or, any didactic declaration or exhibition of God's disapprobation of sin, would open the way for the safe pardon of sinners. Or, if the demands of justice were easily satisfied; if partial, imperfect obedience and fatherly chastisements, or self-inflicted penances, would suffice to satisfy its claims, then the sinner need not be just with God in order to be saved. But the human soul knows intuitively that these are refuges of lies. It knows that there is such an attribute as justice. It knows that the demands thereof are inexorable because they are righteous. It knows that it cannot be saved unless it be justified, and it knows that it cannot be declared just unless the demands of justice are fully satisfied. Low views of the evil of sin and of the justice of God lie at the foundation of all false views of this great doctrine.
