Prayer for my catholic friend dave and my former housemates

My housemates need Jesus and so do my former ones, One of them was gay and my recent housemate is on drugs. It is so potent that I can smell it when I come up the stairs. I have left tracts, he also treats his girlfriend badly and i am stuck what to do. My housemate prays to mary and I have got he has got himself to read his bible. My former housemates are a fountain full of problems they had extreme sexual problems, the thing I want prayer for is that they will turn to jesus. I have had also had problems with my exams and my coursework, the amount of stuff that I went through that term I could write a book. I need jesus and to obey him DomThis site is so cool!!
