How do we know our sins are pardoned according to Scripture?

The assurance of the pardon of our sins is rooted in the work of Christ, who bore our sins in His body on the tree, as stated in 1 Peter 2:24. This doctrine affirms that Jesus, as our substitute, faced the wrath of God on our behalf, securing forgiveness for those who believe. Furthermore, believers find confidence in God's testimony of redemption, which assures us that our names are written in the Lamb's Book of Life, as revealed in Scripture. It is through the grace and calling of God that we come to the realization of our justified state before Him, acknowledging the essential role of Christ's sacrifice in granting us eternal life and unbroken fellowship with God.
