Dad suffering from cancer prayers needed

So
My dad has multiple myeloma cancer. It is a cancer of the blood where you over produce the plasma cell, which makes antibodies freak out basically. the cancer also eats the red blood cells. It causes your bones to be paper thin and for you to develope holes through our your spin. He was originally diagnosed in March 2014. He is in the last stage of the cancer aka the worst level of it. When he first went into the E.R he thought he had kidney stones, but reality he had cance rand the kidney pain was because he was in organ failure. He did the chemo and stem cell transplant. It was suppose to last two to ten years, it lasted my father four months. March of 2015 he was back in the hospital. They have tried experimental chemo but it hasn't worked. He went back in the hospital yesterday. Yesterday his kidneys were failing. The cancer has also caused his diabeties explode, he now has to use insulin. Prayers are needed greatly. He needs prayers of healing to see my sister grow up (she's 11) to see me and my husband have kids and to grow old with his wife. My dad is a good man, he has always worked himself to the bone to make sure we had a decent life. We may have not grown up rich but he always found a way to give us what we wanted. He is a stern man who doesn't show emotions but this cancer has made him into a softer man. He literally bawled his eyes out yesterday, I have NEVER seen my dad cry EVER!!!!
