Why is the altar significant in measuring the temple?

In Revelation 11:1, the altar is specifically mentioned in conjunction with the temple, symbolizing the place of sacrifice and atonement. It serves as a reminder of Christ's crucifixion and His role as the ultimate Lamb of God who took away the sins of His people. This concept is echoed throughout the Scriptures, such as in Hebrews 10:26-31, where the importance of Christ's finished work is emphasized. The altar portrays the bloodshed of Christ, which serves as the foundation for all true worship within the spiritual kingdom, affirming that the worshippers who gather in the temple are those who have been redeemed and washed by His sacrifice, indicating their identity as part of God’s holy nation.
