One of my friends told me, 'You write what I'm too afraid to say.' 2 Timothy 1;7 ''For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline.'' We often shy away from subjects that make others and ourselves feel uncomfortable about, but that doesn't mean it's not worth talking about. I don't mean in your face, down your throat bullying conversations either. Gentle and thought provoking discussion should be on the level of your counterpart.
There is no question and answer that matters more than, 'If you died today, do you know where you'll spend eternity?' Most people avoid this question, because they feel it's too personal to ask. As a believer, it is up to you to speak the truth to others and help rid others of false ideas. It is never left up to us to 'save' anyone, but we can lead others to Christ with our testimony, our conversations and our lives.
On another note, I also encourage 'real' conversation among your fellowship of believing friends. We are all guilty of the 'How are you? Fine' conversation that ends there. We need to know one another better so that we can actually have a heart that cares about one another's life issues.
