Apocalypse Explained # 456
456. Standing before the throne and before the Lamb, signifies those in the Lord's kingdom. This is evident from the signification of "throne," as being, in reference to the Lord, heaven and the church (of which above, n. 253. That "the Lamb" means the Lord in relation to the Divine Human may also be seen above n. 314; consequently "standing before the throne and before the Lamb" signifies that they are in the Lord's kingdom. The Lord's kingdom is heaven and the church, where the Lord is worshiped, and where the Divine in His Human is acknowledged; all who acknowledge this in heart are in heaven and come into heaven; it is said those who acknowledge this in heart, since no one can acknowledge it unless he is in the good of life, and thence in the truths of doctrine. On the earth many can say this with the mouth, but yet they cannot acknowledge it in heart unless they live well; while after the life in the world only those who are in heaven and are coming into heaven can even say this with the mouth, still less acknowledge it. But more respecting this elsewhere.
