"Communing thus with God, Enoch came more and more to reflect the divine image. His face was radiant with a holy light, even the light that shineth in the face of Jesus. As he came forth from these divine communings, even the ungodly beheld with awe the impress of heaven upon his countenance. GW 52.2"
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord."
Both passages discuss reflecting the divine image and a radiant face as a result of communion with God. The connection is more than just thematic, as it specifically mentions the face reflecting God's glory.
"His faith waxed stronger, his love became more ardent, with the lapse of centuries. To him prayer was as the breath of the soul. He lived in the atmosphere of heaven. GW 52.3"
"Pray without ceasing."
EGW's statement about prayer being like breath and living in the atmosphere of heaven directly reflects the principle of constant prayer advocated in 1 Thessalonians 5:17.
"As the scenes of the future were opened to his view, Enoch became a preacher of righteousness, bearing God's message to all who would hear the words of warning. In the land where Cain had sought to flee from the divine presence, the prophet of God made known the wonderful scenes that had passed before his vision. “Behold,” he declared, “the Lord cometh with ten thousands of His saints, to execute judgment upon all, and to convince all that are ungodly among them of all their ungodly deeds.” [ Jude 14, 15 .] GW 52.4"
"And Enoch also, the seventh from Adam, prophesied of these, saying, Behold, the Lord cometh with ten thousands of his saints,"
EGW directly quotes Jude 1:14.
