And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,... Revelation 14:6
"While the sanctuary typology set the system in line with the unfolding
plan of salvation, the three angels' messages placed it within the
framework of the historical-cosmic controversy between God and His
followers and Satan and his followers.
In the inner dimension, both the
sanctuary and the three angels' messages provided the framework for
inner integration of the main components of the Sabbatarian system."
