βIs the remission of sins the same thing as the forgiveness of sins?β
Bible words can often be defined by the way New Testament writers quote the Old Testament. For instance, we know that the wordsΒ deliveranceΒ andΒ salvationΒ are the same, for when Paul quotes Joel, he changes the word βdeliveranceβ to βsavedβ (Joel 2:32; Rom. 10:13). In the same way, we know thatΒ remissionΒ andΒ forgivenessΒ are the same, for in quoting Jeremiah, the writer of Hebrews changes the word βforgiveβ to βremissionβ (Jer. 31:34; Heb. 10:17,18).
In addition, we know that God set Christ forth βto be a propitiationβ¦ to declare His righteousnessΒ for the remission of sins that are pastβ (Rom. 3:25). Thatβs not talking about the sins that are past in your life, thatβs talking about the remission of the sins of Old Testament saints like Abraham and David. So when we read that Abraham was also βjustifiedβ (Rom. 4:1-3), and David was βforgivenβ (Rom. 4:7), we have to conclude that the remission of sins is tantamount to justification as well as forgiveness.
Finally, if you look up the word βremitβ in a good dictionary, one of the words used to define it is βforgive,β and vice versa. source
