See EGW comment on 1 John 1:7, 9.

 Christ, the heavenly Teacher, will lead His people to the tree of life that grows on either side of the river of life, and He will explain to them the truths they could not in this life understand. In that future life His people will gain the higher education in its completeness. Those who enter the city of God will have the golden crowns placed upon their heads. That will be a joyful scene that none of us can afford to miss. We shall cast our crowns at the feet of Jesus, and again and again we will give Him the glory and praise His holy name. Angels will unite in the songs of triumph. Touching their golden harps, they will fill all heaven with rich music and songs to the Lamb (Manuscript 31, 1909).
