How do we know Christ's sacrifice releases us from our sins?

We understand that Christ's sacrifice releases us from our sins as He was the sinless one who bore our debt on the cross. The law's demands, which we could never fulfill, were completely satisfied by Christ's atoning work. In Hebrews 10:17, God promises that our sins and iniquities He will remember no more, signifying complete forgiveness. This profound truth reassures us that through faith in Christ, we experience the Lord's complete release from the guilt and penalty of our sins, a promise that underlines His grace toward His people.
