The central object of the tabernacle was the Arc of the Covenant. This was an oblong box made of acacia wood and overlaid with Gold. In this box together with a pot of manna and the rod of Aaron reposed the Law of God which demanded the death of the Israelites. They had broken that law even before Moses had brought it down from the mountain, and that broken Law demanded death. God had made a provision whereby the guilty ones could be spared from death and the penalty of the law. this provision was a mercy seat which rested on top of the arc which contained the Law of God. This mercy seat was a cover made of beaten gold with two Cherubim overshadowing it. This mercy seat was of no avail until the High priest had taken blood from the altar and sprinkled it on the mercy seat over the arc and then when Jehovah came down upon the arc in the Shekinah cloud, He did not see the law but instead the blood and the law was satisfied. And God was reconciled and instead of the curse of the Law He now brought the blessing of the blood for He had said “When I see the blood I will pass over you.” There can only be one escape from the curse of the law and the penalty of sin and that is the blood. Take away the blood and death falls. Remove the blood from the Bible and it dies as surely as when you remove the blood from a human body. There can only be one place of shelter and that is under the blood.
