So this shows the saints were changed before the end of Rev. return.
ch 3 / 1 John
2: Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
17:15: As for me, I will behold thy face in righteousness: I shall be satisfied, when I awake, with thy likeness.
For we through the Spirit wait for the hope of righteousness by faith.
2 Cor. 5
21: For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
