How do we know Jesus Christ's sacrifice is sufficient for our sins?

The sufficiency of Christ's sacrifice can be seen through the typology found in Genesis 37, where Joseph's blood-stained coat represents the atoning blood of Christ. Just as Joseph’s coat, dipped in goat's blood, presented to Jacob signifies death and loss, Christ’s blood assures us of reconciliation with the Father. 1 Peter 2:24 says that Christ bore our sins in His body on the tree, emphasizing that through His suffering and death, He provides complete atonement, allowing us to come to the Father without guilt. This is supported by the teaching that Christ's blood speaks peace, declaring the finished work of redemption for all who believe, reinforcing the assurance of salvation and eternal life in Him.
