We must share and share abundantly. If we do so, God will provide for us. If you realize the Bible's teachings are correct after the Rapture , don't despair. It is not too late for you. Read the Bible and get up to speed.
Revelation speaks of a Great Deception.
Stan and I have discussed endlessly what form this might take. There are numerous situations where Satan can easily deceive those not on guard. It is an excellent chronicle telling how we are being led into the greatest deception of all time. Start reading the Gospels. After reading Matthew, Mark, Luke and John, you might want to skip to the last book, Revelation, so you can understand what's happening - where everyone has gone and what else to expect.
