David Duncan:
What is it that is blinding Christians today from realizing that Jesus has already brought the kingdom and that the kingdom is here?
Bad Teaching. What version of the new covenant have you been taught?

RJS:
I think that man’s tendency to want to reduce God Almighty in any way is the culprit. Human apprehension can reach to the stars but God Himself cannot be compelled to do anything, given that He has done all that needs to be done.
