[Example] Time [“of” the world (yoked)] Spending your time impulsively or selfishly on whatever you feel like doing, believing it is YOUR time to use as you please without regard to God you could be unequally yoked to a goal, hobby or activity that also consumes the time you should set aside for God [“in” the world (not yoked)] 
Spending your time in activities other than “church” or Christian service such as sports, hobbies, leisure always keeping in mind that we are to be good stewards of the time God has allowed us
