The reason I did not just answer your question--is because--as Christ also often did, I simply gave you the answer according to the issue at hand, rather than what you believe is the issue at hand.Why can't you just answer my question instead of asking your own question? Answer mine first. I asked: What do you mean that the seventh trumpet "sounds the seventh day of God"?
But to answer your question--that I might be clear: The seventh trump sounds the seventh day as foretold from the beginning, in the seven days of creation. In other words, the seventh trump begins the eternal rest of God and all those who are in Him in Christ. Which is also the beginning of eternal damnation for those who are not in Christ.
