Christians, do you not know that you're not supposed to use your brains?

Christians are not supposed to plan or prepare. God will provide (“Take no thought for your life, what ye shall eat, or that ye shall drink; nor yet for your body, what ye shall put on... Behold the fowls of the air: for they sow not, neither do they reap, not gather into barns; yet your heavenly father feedth them. Are ye not much better than they?” --Matthew 6:25-34 & Luke 12:22-31 inclusive). I see Christian conservatives plot on a daily basis how to screw their employees so they can reap more profits.
