"It was while preparing a sermon from Revelation 21 for advent Sunday that the light of Christ's second coming broke in upon Bengel's mind. The prophecies of the Revelation unfolded to his understanding as never before. Overwhelmed with a sense of the stupendous importance and surpassing glory of the scenes presented by the prophet, he was forced to turn for a time from the contemplation of the subject. In the pulpit it again presented itself to him with all its vividness and power. From that time he devoted himself to the study of the prophecies, especially those of the Apocalypse, and soon arrived at the belief that they pointed to the coming of Christ as near. The date which he fixed upon as the time of the second advent was within a very few years of that afterward held by Miller. GC 363.3"
"And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea."
The EGW passage directly mentions Revelation 21 as the source of Bengel's inspiration regarding the second coming. This is a clear and direct connection.
