Even the disciples had to be convinced through miracles and much wisdom.<quoted text>
So, God only ever revealed himself to people who already believed in him and didn't need convincing of his existence? Fascinating. So, every convert from atheism who makes such a claim is a liar. Neat.
But don't concern yourself because JW's believe atheists will get exactly what they ask for,..which is....nothing!
The properties of dark energy is that it is a powerful force that controls the universe, that is unseen and unexplainable that is invented by those that need 'it' to be, so they can maintain faith in their cosmology.
I suppose it is only atheists that give themselves leave to have faith!
