If you curse other people, you #curse 2 people at a time: the other person and you. Yes you include yourself in the curse even if you think not. Why? Because whoever curses someone will not be pleasing in the eyes of God. Why? Whatever comes out of us can defile us especially when our insides are dirty. Jesus said to bless and pray for your enemies. Usually those include people you hate and who do/did bad things to you.
As I said, the people who hurt you need prayers the most. They hurt others because they are hurting inside, whether they want to admit it or not. So when you choose to cuss and hate strangers or family members for whatever reason, and they do not pray for you at all, well, it's both your loss. So... watch this for practical advice on how to do it. 😉
