Question about Romans 3:25-26

[OwenHeidenreich]

25 God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished— 26 he did it to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus.

and I am wondering which sins he is talking about, and who did them?

I believe this is talking about all of the sins from the Garden of Eden until Jesus gave Himself on the cross. Meaning that God tolerated the situation, Knowing that the debt would be paid at Calvary.

Its all of the worlds sin which has gone unpunished or unforgiven.
