What does the Bible say about the altar in Exodus 27?

The altar described in Exodus 27 is central to the worship practices in the tabernacle, symbolizing the necessity of a blood sacrifice to worship God. It was the very first structure one would encounter upon entering the courtyard, emphasizing that no one could approach God without first passing by the altar. This emphasizes that worship cannot be initiated without acknowledging the sacrifice required for sin. In this way, the altar serves as a poignant reminder that the ultimate blood sacrifice for our sins was provided in Christ, who fulfilled this divine requirement once and for all.
