Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;

God presented Him as the atoning sacrifice through faith in His blood, in order to demonstrate His righteousness, because in His forbearance He had passed over the sins committed beforehand.

And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.

Not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.
