Either thru:

•Ignorance [lack of knowledge];

•Choice [tried the ways of GOD and found them wanting];

•Think they know better [choose to rely on their own (GOD-GIVEN) resources/strengths].

You think GOD has granted you those abilities, in excess so you can simply live a life in excess???? HE GAVE IN ABUNDANCE that you might share [turn those blessings into spiritual blessings for yourself by being a blessing to the less fortunate]. IS IT REALLY SO HARD A CONCEPT TO GRASP PEOPLE???
