16. This means that two opposite effects emerged when a true servant of God
radiated the light which made it possible to distinguish true from false and
right from wrong, and made the straight way distinct from the ways of error.
To those endowed with true perception, all truths became evident. But those
who were almost blinded by the worship of their animal desires perceived nothing.
The expression, 'Allah took away the light of their perception' should not create
the impression that these people were not responsible for their stumbling into
darkness. Only those who do not seek the Truth, who prefer error to guidance
and who are adamantly disinclined to pursue the Truth despite its luminosity,
are deprived, by God, of the light of their perception. God simply enables such
people to do what they wish.
