If the NT is a bunch of lies - end of discussion. But let's consider that The NT is true: Then Jesus was resurrected and before ascending to heaven, he was seen by few and after he ascended he communicated with Paul and John and gave evidence of his presence. Point is that there was solid evidence - but not to everyone. The ironic scripture and one of my favorites "The kingdom of God is in your midsts." -People can't see the hidden elephant in plain sight. After Jesus was resurrected, there was no main concern about healing the blind , etc. or ending human suffering. The main focus was to establish a church and to spread Chrisianity all over the world. Jesus was at first according to the scriptures with the Christian movement but then xtians became lion food and the movement continued until the sword to a persons neck transformed a person to xtianity. For aprox a couple thousand years, the movement continued all over the world through Babylon the Great using the inquisition, the crusades and other methods of conversion to Christianity. -Absolute horror! : the native Americans, the Blacks, any creature that opposed the Church, etc. -Then came 1914 to an already Christianized world, the end of the Gentile Times, Jesus appears again and the main concern is the church and the JW Christian movement.
But here is the thing, the evil that the xtian church has done does not invalidate the good that Jesus taught and did or Bible Christianity. The question is why did Jesus not stay with the church he started in 33 CE? Assuming the NT, the only logical answer is Satan, Gentile Times, -and the Parousia at a later date. ( not saying this later date is 1914 )
