Psalm 119:10: With my whole heart have I sought you; O let me not go astray from your commandments.
One of the bad things about living in a bad area or amongst bad people is that you get exposed to so many bad things that you begin to accept certain things as being normal.
I use 'bad' in a very broad way because we all have different definitions of what bad is - because we all grow up in different areas and are exposed to different things!
God wants us to realise we can get carried away with the things going on around us, so the easiest way to not get involved is to stay away from those things...
But that is not so easy because we live in a world where there are so many different things and experiences.
