【Adore】 , 【worship】 and 【idolize】 in their nonreligious senses mean to love or admire excessively.

【Adore】 commonly implies emotional surrender to the charms or attractions of an object of love or admiration; it often connotes extreme adulation if the object of love is a person.

【Idolize】 often implies absurdly excessive admiration or doting love.
