Dr. Couch, thank you for sharing the fact that Christ's sacrifice was applied back to the sins of those in the OT, as you pointed out in Romans 3:25b. Are there any other verses that would show this same point as well?
Yes, and that would be Hebrews 9:15b. The author of Hebrews writes: Christ "died for the redemption of the transgressions that were committed under the first covenant (the Law), [that] those who have been called may receive the promise of the eternal inheritance."
Kenneth Wuest rightly notes:
The Messiah became the Mediator not only in order that He might pay the penalty of sinners who live since the Cross, but also that He might do so for those who lived before the Cross. Sinners who were saved under the First Covenant were actually saved, not by it or by any sacrifice offered under its jurisdiction, but through the atoning work of Messiah under the New Testament.
Thanks for asking.
Dr. Mal Couch
