What does the altar in 2 Samuel 24 symbolize?

The altar built by David at the threshing floor of Arunah serves as a profound symbol of reconciliation between God and His people through sacrifice. In offering burnt and peace offerings, David's actions point to the ultimate sacrifice of Christ, who, as our perfect Lamb, takes away the sins of the world. This moment reinforces the historic Reformed understanding that without the shedding of blood, there is no remission of sins (Hebrews 9:22). The altar signifies both the cost of sin and the immeasurable mercy of God, who stays the plague as a result of David's humble offering, showcasing the importance of recognizing Christ as our ultimate atoning sacrifice.
