The Revelation of "the Mystery"
Through Christ (who was the sin-offering that God first told Cain about, which God would place on the altar at the door of the Garden by grace) through that offering the whole barrier system was to be abolished. Instead of a step-by-step expelling of man eastward into relative oblivion (as happened with Adam, Eve, Cain, the antediluvian world, and those at the tower of Babel), all the barriers to God as shown by the temple (and the Garden) were to be removed in Christ. Paul said, "The middle wall of partition" has now been broken down (Ephesians 2:14). This means that the Gentiles (like Cain) who were in a state of wandering and without any fixed spiritual home, can come into the court of Israel where the altar is located. This got them back to Eden. But there is more than simply getting access to the holy altar.
Once the "sin-offering at the door" is accepted they can join hands with Israelites (with both peoples now called "the new man" — not Israelite or Gentile), and both walk up the fifteen steps into the Holy Place. The Cherubim no longer will keep them out with their flaming sword. They are now back in the Garden from whence our first parents were expelled. But that is not the end. When Christ died on the cross, the curtain in the temple that separated the Holy Place from the Holy of Holies ("the midst of the Garden") was supernaturally torn in two from the top down (Matthew 27:50–51). In Hebrews we are told that the destruction of this final barrier now gives us "boldness to enter into the holiest [the Holy of Holies] by the blood of Christ ... through the vail" (Hebrews 10:19–20).
"Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need."
What glorious teaching! All the obstacles that God set up in a progressive sense to alienate Himself from man (in a spiritual way) from the time of Adam and Eve onward, He has systematically abolished through the work of Christ Jesus.
"Having ABOLISHED in his flesh the enmity, even the law of commandments contained in ordinances [decrees of separation]; for to make in himself of two one new man, so making peace."
All the commandments and decrees which God formerly ordained to separate Himself from various peoples, have been removed in Christ. Adam and Eve, Abel and Cain, Israelite and Gentile, you and I, are now back "in the Garden" — and now in the very midst of it. We do not even have to wait for "the cool of the day" to come into contact with our Father. We now have a constant presence — in a spiritual sense. And the day is soon coming when we ourselves will be spirit beings (1 Corinthians 15:42–55).
When that day arrives, we will not only be able to talk with God face to face as did our first parents, but "we shall be like him; for we shall see him as he is" (1 John 3:2). As God is Spirit, so will we be. We will then be "as he is" — as His own Spirit-born children. This is far more glorious than it was with our first parents. Indeed, reaching this position is the very purpose for living. Our experience with sin, with an alienation from God, with suffering, will help us for all eternity to love God our Father in a much greater way than our first parents were able to experience. What a glorious future awaits mankind through Christ.The Holy of Holies is now open to all people on earth without social, racial, or outward religious distinction. It is Christ who has redeemed Adam and his family to Himself. Christ's death on the cross and His resurrection from the dead are mankind's guarantee of a certain salvation. It comes to us by God's grace, not man's works. One day all humanity will understand this truth.
