How do we know that Christ has purged our sins?

Hebrews 1:3 tells us that after making purification for sins, Christ sat down at the right hand of God, highlighting the finality of His atoning work. The act of sitting down represents that His sacrificial work is complete; there is nothing left for us to accomplish in order to secure our salvation. The purging of our sins is not a metaphorical idea but a profound reality; our sins are completely gone because of Christ's finished work. Therefore, if you have placed all your hope in Him, your sins are not just covered but eradicated.
