The answer is: Hebrews

Hebrews 9:22 - This verse explains the necessity of bloodshed for atonement, fulfilled ultimately in Christ’s sacrifice.

In the book of Hebrews, that key verse about the shedding of blood speaks volumes about ancient customs and spiritual truths. To grasp its significance, let's remember that the practice of animal sacrifices was central to Jewish culture. They believed that the life of the flesh is found in the blood, and it symbolized life and atonement for sins (as seen in Leviticus 17:11).

In Hebrews, the author draws a fascinating connection, asserting that Jesus’ sacrifice transcends those old rituals. This demonstrates a radical shift in understanding forgiveness—no longer tied to blood and goats but instead embodied in the life and death of one person: Jesus. This belief plays into the broader context of covenant theology, where new covenants supersede old ones, opening the door to a more personal connection with the divine.

Interestingly, Hebrews is a unique New Testament book, with its soaring rhetoric and rich imagery often drawing parallels between Christ and the Jewish sacrificial system. It invokes the concept of “the High Priest,” likening Christ to the highest religious authority, and argues that His sacrifice wasn’t merely another ritual, but a profound and transformative act for all of humankind.
