"Peter kept alive in his heart the hope of Christ's return, and he assured the church of the certain fulfillment of the Saviour's promise, “If I go and prepare a place for you, I will come again, and receive you unto Myself.” John 14:3 . To the tried and faithful ones the coming might seem long delayed, but the apostle assured them: “The Lord is not slack concerning His promise, as some men count slackness; but is long-suffering to usward, not willing that any should perish, but that all should come to repentance. But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. AA 536.1"
"And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also."
Ellen White directly references John 14:3 in this passage.
"“Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? Nevertheless we, according to His promise, look for new heavens and a new earth, wherein dwelleth righteousness. AA 536.2"
"Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,"
The EGW passage directly quotes 2 Peter 3:11, making it a clear and explicit allusion.
