For the law was given by Moses, but grace and truth came by Jesus Christ. – John 1:17

In the gospel of Jesus Christ grace is the most predominant attribute of God. How comes it to be so exalted? We reply, well, grace has a throne by conquest. Grace came down to earth in the form of the Well-beloved, and it met with sin. Long and sharp was the struggle, and grace appeared to be trampled under foot of sin; but grace at last seized sin, threw it on its own shoulders, and, though all but crushed beneath the burden, grace carried sin up to the cross and nailed it there, slew it there, put it to death for ever, and triumphed gloriously. For this cause at this hour grace sits on a throne, because it has conquered human sin, has borne the penalty of human guilt, and overthrown all its enemies.

There is no injustice in the grace of God. God is as just when He forgives a believer as when He casts a sinner into hell. I believe in my own soul that there is as much and as pure a justice in the acceptance of a soul that believes in Christ as there will be in the rejection of those souls who die impenitent, and are banished from Jehovah’s presence. The sacrifice of Christ has enabled God to be just, and yet the justifier of him that believeth. He who knows the word “substitution,” and can spell its meaning aright, will see that there is nothing due to punitive justice from any believer, seeing that Jesus Christ has paid all the believer’s debts, and now God would be unjust if He did not save those for whom Christ vicariously suffered, for whom His righteousness was provided, and to whom it is imputed. Grace is on the throne by conquest, and sits there by right.~ C.H. Spurgeon
