I am a christian,one of the most devote christians in my family.However one person in my family seems to be a constant problem in my family. He is an angry person who uses mental abuse and physical threats to impose is will on my family. I am the only one in my family that can handle him physically.I have tried to talk to him regarding god and scripture,but he becomes distant and blocks it out. He always gets a look on his face,like he would rather me shutup.He uses my christianity against me, thinking because i am a christian that he can do what ever he wants to my family and no one can stop him. He knows i think its wrong to fight ,but he's not leaving me much choice. Whats the best course of action here?
