Grow up!

A 'narcissist' has been described as: "...a person who is overly
self-involved, and often vain and selfish." These characteristics
are a normal for young children--but not for mature adults!

A twenty-first century summary of Paul's teaching in today's verses
might be: "Grow up, people: Don't act like a narcissist! This life
is not all about you. Have compassion for your brothers and sisters
because you are responsible to the Lord for them."
  
  But you must be careful with this freedom of yours. Do not cause a
  brother or sister with a weaker conscience to stumble. You see, this
  is what can happen: Weak Christians who think it is wrong to eat
  this food will see you eating in the temple of an idol. You know
  there's nothing wrong with it, but they will be encouraged to
  violate their conscience by eating food that has been dedicated to
  the idol. So because of your superior knowledge, a weak Christian,
  for whom Christ died, will be destroyed. And you are sinning against
  Christ when you sin against other Christians by encouraging them to
  do something they believe is wrong. (1 Cor 8:9-12 NLT)
