How do we know Jesus took away our sins?

The assurance that Jesus took away our sins is firmly rooted in Scripture. 1 John 3:5 declares that Christ was manifested to remove our sins, and it emphasizes the truth that in Him, there is no sin. Additionally, 1 Corinthians 15:3-4 articulates the gospel message that Christ died for our sins in accordance with the Scriptures and was resurrected. This gospel assurance bolsters our faith and confidence that His sacrifice was sufficient for the redemption of His people, aligning perfectly with the truth of sovereign grace.
