Eschatology is simply an intellectual study of the end times events. It is defined by 4 different viewpoints normally. Yet this is all but unfruitful, if we do not follow Jesus Christ in Spirit and in Truth. Lean not to your own understanding, but in “all things” bring it before the Lord. Most will not, nor can not do this, as you must know someone in order to follow them – and in the end days, most do not know the Lord. 2 Thess 2 -Satan must come first, and then Christ returns for his Bride, not the Harlots of Rev 17-18!
This video is speaking about how Satan takes great pleasure in defiling anything which once claimed the name of Jesus Christ. Michael Wurmbrand in his letter specifically asked that we share his message with as many as possible in honoring his family name.
Sin is what separates us from Christ, even when we have come to him, and we must learn to walk in only Him who dwells within us!
This is the narrow way which Jesus spoke about, and no man made organization is able to hold Him: that is the Disciples job to do, and Revelation 17 reflects why.
