Good Definition of faith and armour of God

SOME TIME AGO I REMEMBER MR. ARMSTRONG
SAID, DO YOU KNOW WHAT FAITH IS? FAITH
IS IF YOU WANT TO MOVE THE EIFFEL TOWER — OR
WHATEVER IT WAS YOU WANT IT TO BE MOVED —
YOU GO AND PUT THE CORD AROUND IT AND START
PULLING IT. IF IT MOVES THAT’S GOD’S DOING IT. BUT
YOU STILL HAVE TO DO YOUR SHARE.
NOW IF WE WANT TO GET THE EIFFEL TOWER
MOVED AND WE JUST SAY MOVE, IT DOESN’T DO
ANYTHING BECAUSE WE’RE NOT DOING ANYTHING.
WE HAVE TO DO OUR JOB, AND IF IT HAPPENS,
THAT’S GOD’S DOING IT. NOW THIS SAME PRINCIPAL
APPLIES TO THE ARMOUR YOU HAVE TO PUT ON.
YOU HAVE TO GO AND FIGHT LIKE DAVID. GET THE
SWORD AND SWING. IF ANYTHING IS ACCOMPLISHED,
IT’S GOD’S DOING.
