In His ascension Christ poured out Himself as the consummated Triune God and as the all-inclusive Spirit upon His members, to constitute all of them into one organic Body to be the organism of the processed and consummated Triune God. This is the church as the new man, as the Body of Christ, and as the organism of the Triune God, and this entity will consummate in the New Jerusalem. Thus, in God's long answer to Job's suffering there are ten main items: incarnation, human living, crucifixion, resurrection, ascension, the church, the new man, the Body of Christ, the organism of the Triune God, and the New Jerusalem.
The main contents of the New Testament are that the Triune God has an eternal economy according to His good pleasure to dispense Himself into His chosen and redeemed people in His life and in His nature, to make all of them the same as He is in life and nature, to make them His duplication that they may express Him. This corporate expression will consummate in the New Jerusalem. Thus, the New Jerusalem is simply the enlarged, the increased, incarnation consummated in full, that is, the fullness of the Triune God for Him to express Himself in His divinity mingled with humanity. These are the contents of the New Testament, and this is the answer that Job needed. This is God's answer concerning the purpose of Job's suffering.
