(It just dawned on me how old brett looks in the video.) In all fairness though, the video is not actually about it being too late to return to Jehovah.
The garbage in the video alludes to Gehenah and WT says that only JHV sees the heart not the WT and it is he that can put someone there not the WT, but the garbage (gehena) is a warning because the danger to be thrown there exists -at least that is what Jesus says in the NT not the WT-and the NT gives specific examples of such sin.The sin is rejecting evidence from God, his Holy Spirit which was evident as Jesus showed, namely the maliciousness of the Pharisees, etc.The exact same evidence exists today. Anyone who fights against God's Holy Spirit, solid proof from God must answer to God, face Gehena. That is what the video is about. I may add that Jehovah is a God that is very peculiar about vengeance, particularly towards those who make trouble for his friends. The Bible records how Jehovah curses and plagues and becomes at war with and even exterminates any entity that threatens or causes any harm whatsoever to his friends. That is from the Bible not from the WT,
