Most by now have heard of Jesus Christ, some way or another, yet some do not believe. It may take great hardship/tribulation for them to even seek the truth or at least hope for a Savior.
God does not wish any to perish. Some are wooed to the gospel because it easily speaks truth to one's heart and others need more proof before they will believe. Tribulation normally always gets people's attention....foxhole experiences come to mind.
I keep an open mind to the ways of how God will work in the endtimes. There could be a literal star that falls or there may not be. People should keep their bibles open and in personal prayer at all times seeking the signs and seasons....not the day. Each person is responsible for his own studies and understanding and should not ever just believe another because one is too lazy or thinks they could never understand on their own. If asked with a sincere heart, God will help one be guided.
Just like many of us will quote or add posts written by others...the one who is reading is still responsible for seeking the truth for themselves. We only post to make people more aware of our world in prophecy and God's presence. The Word and His Spirit are the true guiding light in this dark world of unknowns.
The one's who will be judged harshly are those who purposely try to deceive the world for their own gain.
