What does the Bible say about God's altar?

The Bible emphasizes that any worship must occur at the altar God has designated, as illustrated in Leviticus 17. This passage highlights that sacrifices should be brought to the door of the tabernacle, where they are offered to the Lord. The act of offering sacrifices elsewhere is considered idolatry, as it denies God the glory due to Him for His prescribed means of worship. God has established a specific way for His people to worship Him—through the blood of Christ, demonstrating that worship outside of this prescribed method is futile and dishonoring to God.
