I'm going to tell a homeless that jesus does not help him
Why do you want to tell him that Jesus doesn't want to help him?
I do not want to be friends with someone who believes in god
I understand that you don't believe in God, but you shouldn't impose your beliefs on others. Let him have faith in Jesus to help him in his life.
Fuck that. I know better than he does. Good thing he's not my friend or else I would be bad to him.
You need to understand this person is going through a rough time and if faith gives him some comfort you should respect that. It's ok you don't believe in it but you should learn to respect views different than yours. There is no harm in believing Jesus will help.
