what I understood: 得救 只靠神 不靠人, I agree, 神人和作,
what man do because of what God do (God Father planned, God Son completed, God Spirit helps us to achieved), as a result, we believe in Him so that
we are promised to be leaded to the new Jerusalem,
otherwise,
man is directly heading to hell happily joyfully willingly unfeelingly
(this is man's freedom. natural man no longer have freedom go other way
opposite).
