If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. -1John 1:9
When the soul is seriously impressed with the conviction of its guilt, when terror and alarm get hold upon it concerning the inevitable consequences of its sin, the soul is afraid of God. It dreads at that time every attribute of divinity. But most of all the sinner is afraid of God’s justice. “Ah,” saith he to himself, “God is a just God; and if so, how can He pardon my sins? for my iniquities cry aloud for punishment, and my transgressions demand that His right hand should smite me low. How can I be saved? Were God unjust, He might forgive: but, alas! He is not so, He is severely just. ‘He layeth justice to the line, and righteousness to the plummet.’ He is the judge of all the earth, and He must do right. How then can I escape from His righteous wrath which must be stirred up against me?”…It is true that God is just…let hell’s bottomless lake declare what is the awful vengeance of God against the sins of man. Let the sighs, and groans, and moans, and shrieks of spirits condemned of God, rise in your ears, and bear witness that He is a God who will not spare the guilty, who will not wink at iniquity, transgression, and sin, but who will have vengeance upon every rebel, and will give justice its full satisfaction for every offence.
Wonder ye heavens! be astonished O earth! that very justice which stood in the sinner’s way and prevented his being pardoned, has been by the gospel of Christ appeased; by the rich atonement offered upon Calvary, justice is satisfied, has sheathed its sword, and has now not a word to say against the pardon of the penitent. ~ C.H. Spurgeon
