"In regard to “The Tribulation” though, the Bible is silent. Since God never uses that phrase the way that man does, God does not define it or specifically tell us anything about it. This is problematic."
Actually this is not true. Christians will endure the effects of the first six seals up to the point that the resurrection/rapture takes place and those things are described. Also we are told that many will be overcome by the antichrist, as well as other things we are told in the scriptures.
Amos 3:7 Surely the Lord GOD will do nothing, but he revealeth his secret unto his servants the prophets.
There has been and will continue to be an abundance of prophecy regarding the times soon to come - maybe you you should start to listen to them.
