Of course, I have made many mistakes and fortunately the human species has very successfully survived in spite of their imperfections. I am a human and humans make mistakes. I would, however, challenge anyone telling me that any of those mistakes was a sin. The word' imperfections' is a mistake too - we are obviously very well adapted to living and surviving in more than enough numbers in very many parts of the world.
the reason for the word sin to be questioned of course is that if people believe they have sinned, then the automatic assumption is that there is a God against whom this *sin* has been committed.
Do you differentiate between sin and making mistakes? If you think you have sinned against God, can you say why? Do you use the word sin about yourself? About others? Or is the word, whether verb or noun, absent from your vocabulary?
One of the reasons I ask these questions is that I have been following a very interesting topic elsewhere on Universalism, i.e. God will forgive all sins, or he won't, or he might under certain circmstances, plus the question of whether all will be *saved* whether they want to be or not!!
