Matthew 6:23 But if your eye sees things wrongly, then your whole body i.e., your entire life will be full of darkness i.e., will not be lived properly. If therefore, the light you have is really darkness i.e., if you are not seeing life properly, that darkness will be very great i.e., you cannot possibly live properly.
