"“These things have I spoken unto you in parables,” He said; “but the time cometh, when I shall no more speak unto you in parables, but I shall show you plainly of the Father.” John 16:25 , margin. 8T 267.1"
"These things have I spoken unto you in proverbs: but the time cometh, when I shall no more speak unto you in proverbs, but I shall shew you plainly of the Father."
Ellen White directly references John 16:25 in this passage.
"But the disciples had not yet received the complete fulfillment of Christ's promise. They received all the knowledge of God that they could bear, but the complete fulfillment of the promise that Christ would show them plainly of the Father was yet to come. Thus it is today. Our knowledge of God is partial and imperfect. When the conflict is ended and the Man Christ Jesus acknowledges before the Father His faithful workers, who, in a world of sin, have borne true witness for Him, they will understand clearly what now are mysteries to them. 8T 267.3"
"For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known."
Both passages discuss the partial and imperfect nature of our current knowledge of God, contrasting it with a future, clearer understanding.
"Christ took with Him to the heavenly courts His glorified humanity. To those who receive Him, He gives power to become the sons of God, that at last God may receive them as His, to dwell with Him throughout eternity. If, during this life, they are loyal to God, they will at last “see His face; and His name shall be in their foreheads.” Revelation 22:4 . And what is the happiness of heaven but to see God? What greater joy could come to the sinner saved by the grace of Christ than to look upon the face of God and know Him as Father? 8T 267.4"
"And they shall see his face; and his name shall be in their foreheads."
EGW directly quotes Revelation 22:4.
"But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:"
EGW echoes the principle of John 1:12, that receiving Christ gives the power to become sons of God.
