In Order That Jesus, Through His Atoning Sacrifice, Might Furnish a Meeting Place Between God’ and the Soul, It Was Requisite That He Should Become Incarnate. This Truth Is Set Before Us in the Shittim Wood: THE DIMENSIONS OF THE ALTAR

Five cubits long, and five cubits broad; the altar shall be foursquare; and the height thereof shall be three cubits. Twice the length and height of the ark of the covenant.
These dimensions were fixed by God himself, who also prepared a body for Christ, every way adapted and adequate for his work and sufferings, wherein he has laid the foundations for unbroken communion between God and his people.
