Isaiah 53:9 And he made his grave with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth. 10 Yet it pleased the Lord to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the Lord shall prosper in his hand.
So, the fundamental understanding of forgiveness is that it will cost, some more, some less. Therefore, as the Lord contemplated the huge costs of forgiveness to billions, upon billions of people, it was necessary to create a sort of banking account as it were, so He could store much forgiveness for whenever we may need it.
This account never runs dry because it is centered in Christ, who went over, and beyond to make certain that any amount of forgiveness could be readily and easily deployed to any, and everyone who needs it. This concept of storing forgiveness for whoever may need it, can be found in the book of Exodus, where God says that he “Keeps” mercy for thousands.
And so said, so done, for as the sanctuary system of sacrificial offerings was instituted, God then made provision so that a constant, and a readily available supply of sheep, lambs, goats, and bullocks was on tap, for whenever and wherever forgiveness would be needed. This is the concept of God creating the “Storehouse” or bank account of forgiveness.
Exodus 34:6 And the Lord passed by before him, and proclaimed, The Lord, The Lord God, merciful and gracious, longsuffering, and abundant in goodness and truth, 7 Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation.
May God add His blessing to the study of His word. “Good night” and God bless!
