How do we know Jesus' sacrifice truly forgives our sins?

The assurance of Jesus' sacrifice truly forgiving our sins lies in the doctrinal truths supported by Scripture. Romans 5:8 tells us that 'while we were yet sinners, Christ died for us.' This emphasizes that His death was a willing and complete act of love directed toward all of humanity. Moreover, according to 1 Peter 2:24, 'Who his own self bare our sins in his own body on the tree,' indicating that the transfer of our sins to Christ was definitive and personal. His blood not only redeems but also justifies us before God (Romans 5:9), solidifying the truth that through faith in Him, our sins are entirely forgiven.
