"These visions of future glory, scenes pictured by the hand of God, should be dear to His children. MH 506.1"
"Now faith is the substance of things hoped for, the evidence of things not seen."
Both passages deal with the concept of unseen realities and future hope. Hebrews 11:1 defines faith in terms of unseen things, while EGW speaks of visions of future glory. The connection is thematic, though not a direct allusion.
"Stand on the threshold of eternity and hear the gracious welcome given to those who in this life have co- operated with Christ, regarding it as a privilege and an honor to suffer for His sake. With the angels, they cast their crowns at the feet of the Redeemer, exclaiming, “Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honor, and glory, and blessing.... Honor, and glory, and power, be unto Him that sitteth upon the throne, and unto the Lamb for ever and ever.” Revelation 5:12, 13 . MH 506.2"
"Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing."
EGW directly quotes Revelation 5:12 and 5:13.
"There the redeemed ones greet those who directed them to the uplifted Saviour. They unite in praising Him who died that human beings might have the life that measures with the life of God. The conflict is over. All tribulation and strife are at an end. Songs of victory fill all heaven, as the redeemed stand around the throne of God. All take up the joyful strain, “Worthy is the Lamb that was slain” and hath redeemed us to God. MH 506.3"
"And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;"
EGW directly quotes Revelation 5:9.
