Hi Sopho
Despite what you might have inferred from certain translations and commentaries you have read, I have no doubt whatsoever that there is absolutely nothing wrong with talking about things you enjoy - whether it’s books or sports or gardening or cooking or family life or movies or whatever.
I am pretty sure that what the Apostle is warning us against is ‘idle gossip’ - malicious chit-chat that is harmful to others. If ‘light conversation’ is a sin then we’d all need to be on our knees repenting about 98% of the time we opened our mouths .
Seriously, Sopho, don’t fret about this. And please, continue to enjoy your hobbies and pastimes, and enjoy talking about them.
All the best
Johnny
PS I know you said your conscience is telling you not to do this, but sometimes our conscience does get things wrong. Sometimes we can be trying so hard to do the right thing we end up doing the wrong thing .
