I would agree the greater works seem to reflect salvation
Jesus provided for our salvation but it was not until He ascended that the gospel started going out into all the then 'known world' and of course today, the world
so Jesus did not actually share His own gospel in the manner we do today and He actually only taught in a small area
I would also agree with this verse of scripture
5having a form of godliness but denying its power. Turn away from such as these! II Timothy 3
now the context of that verse says more than may apply to those in this thread that deny the gifts or just about anything they cannot touch, feel, see, smell or observe in some way that connects with their human reasoning
however, I think we are seeing a form of godliness with no power for certain in those who deny the Holy Spirit's 'intrusion' into their carefully plotted 'Christian' path
IMO, they prefer men and their teachings
