How do we know that Jesus' atonement is effective?

The exaltation of Jesus as described in Hebrews 8:1-2 serves as a powerful testament to the effectiveness of His atonement. The logic presented in Scripture indicates that if His sacrifice had failed, He would not have been received on high. His current position at the right hand of God confirms that He has accomplished what He intended through His death and resurrection—putting away sin and satisfying divine justice. This assurance encourages believers to trust in His atonement, knowing that redemption is certain for those who genuinely believe.
