The book of Revelation speaks of a church as a woman, symbolically. It describes a virtuous woman—made up of cleansed, forgiven, and Spirit-filled saints—marrying Christ at His return. But it also speaks of an adulterous woman—filled with blasphemy, fornication, selfishness, and even demonic activity—being punished by plagues from God. Two different women. Two different churches. Which one do you want to be a part of?
Can you prove, from the Bible, who or what the prophesied Antichrist really is? This is not some esoteric topic. Your correct understanding may affect whether or not you will be able to fulfill the role that God has planned for you in His kingdom!
