"These truths, as presented in Revelation 14 in connection with “the everlasting gospel,” will distinguish the church of Christ at the time of His appearing. For as the result of the threefold message it is announced: “Here are they that keep the commandments of God, and the faith of Jesus.” And this message is the last to be given before the coming of the Lord. Immediately following its proclamation the Son of man is seen by the prophet, coming in glory to reap the harvest of the earth. GC 453.3"
"Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus."
EGW directly quotes Revelation 14:12, making this an explicit allusion. The context further reinforces the direct connection.
