I was like that last time too before I really came to know the Lord. Cursing and swearing at almost anything. Now the sickening habit is gone, well almost because I still experience 'repercussions' every now and then when something terrible happens. I won't shout it out but I would like curse in my head and would feel bad after that because I know that this kind of language does not belong to the Lord. But I know that this will eventually be completely eradicated from my life the more I seek Him .
It's not an easy task especially with the people around you and the media constantly hurling vulgarities at everything. But hey, with the Lord's help, nothing is too great for Him to handle.
