"The whole purpose of the great white throne judgment is to clear away all the old religious heavens that have ruled us, and the earth of the flesh and the works of the flesh that have bound us, to make way for God’s new order — the new heaven and earth of CHRIST’S KINGDOM. I do not say that even that heaven and earth are an eternal order, for Paul tells us of a reality beyond all this: “Then cometh the end, when He shall have DELIVERED UP THE KINGDOM to God, even the Father; when He shall have put down all rule and all authority and power…and when all things shall have been subdued unto Him, then shall the Son also Himself be subject unto Him that put all things under Him, THAT GOD MAY BE A-L-L I-N A-L-L!” (I Cor. 15:24,28). That is certainly beyond the new heaven and the new earth of the kingdom of Christ! We experience these things more and more in our lives as we walk with the Lord. This is the ongoing process by which Christ is “making everything new.” By it He transforms us into a new creation in which God can live, work, express, and manifest Himself in the totality of His life, glory, and power. When our old earth and heavens flee from before the Lord’s face, when we allow no room for them in our experience, God’s judging and refining has at last destroyed all carnality, sinfulness, religiosity, and all immature spirituality from our lives."
Much more in the link:
"The judgments of God are first and foremost not external, but internal; not future, but on-going. The Word of God, history, and our own experience shout aloud the truth that the soul’s verdict is even now being written moment by moment, not by recording angels in heavenly books on some distant shore, but by each man himself on the fleshy tables of his own heart. This present life is to each of the consecrated ones his “day of judgment” — his day of trial, testing, proving, chastening, his day of being brought to perfection in Christ. When any man anywhere at any time begins to be dealt with by God to bring him into his full salvation, the “day of judgment” will begin to function in mighty power in his life. The apostle Peter’s words are in harmony with this: “Judgment must begin at the house of God!” (I Pet. 4:17). This passage in the Greek text speaks of the judgment of God flowing out from the house of God; but nothing can flow out from the house of God that hasn’t first become an experiential reality within the house of God. Oh, yes, let all men know that all judgment must begin at the house of God! This does not imply a sudden visitation of catastrophes, calamities, and troubles, but it means that there will be a concentration of divine instruction and discipline, as the Father purifies each individual, until He can gather to Himself a FIRSTFRUITS."
