what is faith?

what is faith? faith is believing in somthing we cant see of feel. think about this , your house set fire and every one was outside it except you, you looked out the window and your dad said jump i will save you. in your mind you are pretty shure he cant,you did not have faith in him thats the same way with God.. most of the time our faith is weak and we dont really believe he can do what he says or what we pray for. right?? but you should pray to god asking him to give u more faith in him and believe he will do it!!!
