difficulties concerning guidance and doubts

8:  "Some, however, may say here, 'But I thought we were not to depend on our unenlightened human understanding in Divine things.'  I answer to this that we are not to depend upon our unenlightened human understanding, but upon our human judgement and common sense enlightened by the Spirit of God."  

9:  "Look right at Jesus, and tell Him that you do trust Him, and that you intend to go on trusting Him.  Then let the doubts clamor as they may, they cannot hurt you if you will not let them in.  I know it will look to you sometimes as though you were shutting your door against your best friends...but deny yourself; take up your cross in this matter, and quietly but firmly refuse ever to listen to a single word."
