Prayer for Richards Mom and Dad

I would like to ask if you would please pray for my mother and step father,They both have lung cancer stage 4,The chemo is really not working as well as they would like,They will try them on a new chemo,I believe that god can heal today as he did yesterday,I know it’s his will,I just pray for healing at this time and i would appreciate all the prayers that we can get,They told my mom a year,It’s up to god not the doctor’s,I thank god for doctor’s but it’s up to god to say when it’s time,I just hope it’s longer than what the docotor’s are saying.Thank’s for the prayers.’
