Adventists have a "vocabulary unique to their belief that is just like the vocabulary one would find in any other church and even in the sciences. Not everyone is fluent in Adventistese. It takes a while to learn and understand the "insider" shorthand that we hear in Sabbath School, church and around the table at potlucks.
Some phrases are innocent enough while others display exclusivity and even and (unwarranted, I think) arrogance. There is need to expunge the arrogance and embrace the innocent.
Back to the point the Third Angel...
The work of the First Angel finished with the announcement of the Judgment. The Second Angel gave a matter-of-fact (not even loud) update on the status of Babylon and its inhabitant Beast, so, the messages of the first and second angels are history; but the work of the Third Angel is future...just not very far in the future. For review, it goes like this; "Then a third angel followed them, saying with a loud voice, 'If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of god, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb..." [Rev. 14:9,10].
In Psalms 75:8 we find a verse that parallels part of the third angel's message; "For in the hand of the Lord there is a cup, and the wine is red; fully mixed, and He pours it out; surely its dregs shall all the wicked of the earth drain and drink down."
Our work; the work of the church; the work of every true believer, is to warn the world of the consequences of having a mark on the forehead (right behind is the frontal lobe of the brain where one evaluates and decides) or in the hand (which is symbolic when one is asked to "lend a hand." to help out even though they may not agree in principle with the project...the frontal lobe...
Think on these important things and "decide" to serve the Lord.
God bless. e.c.
