What does the Bible say about the atonement of Jesus?

The atonement of Jesus is depicted in Scripture as a profound union of His divine and human natures, effectively accomplishing the purpose of salvation for humanity. Acts 20:28 states that the church of God was purchased with His own blood, emphasizing that this blood is not ordinary but of infinite value due to the Deity it represents. Hebrews 1:3 tells us that Jesus purged our sins by Himself, highlighting His unique role as both the Priest and the Offering. This dual nature showcases that while humanity suffered in the sacrifice, it was the divine essence that imbued the sacrifice with its ultimate significance and power to atone.
