Simple Obedience

"People who are more obedient to the general word of God are more prepared to recognize and be obedient to the specific words from God."  -Paul Maconochie

God has already spoken in powerful ways.  His word is potent and prolific.  It is sharper than any double edged sword.  Yet I know my temptation is to whine and bemoan that I have not heard a new and deeper word from God.  Why should God speak a new and deeper word to me when I have not been obedient to the words already spoken?
