God's justice and God's mercy do not quarrel with each other.
Justice is not something God has. Justice is something that God is.
God's justice stands forever against the sinner in utter severity. The vague and tenuous hope that God is 'too kind' to punish the ungodly has become deadly opiate for the consciences of millions. It hushes their fears and allows them to practice all pleasant forms of iniquity while death draws everyday nearer and the command to repent goes unregarded. As responsible moral beings, we dare not so trifle with our eternal future.
When God justifies a sinner, everything in God is on the sinner's side. All the attributes of God are on the sinner's side. It isn't that mercy is pleading for the sinner and justice is trying to beat him to death. All of God does all that God does.
