In John 14:14, Jesus states that "if you ask me anything in my name, I will do it."
Whenever we pray and ask Jesus for help, we should have faith that he will provide.
Our faith should not be accompanied by doubt.
The Lord is our provider, and he will provide us with anything we need as long as we have faith in him.

James 1:6 "ask in faith without any doubting", whatever we ask for in Jesus name, we should act as if we have already got it, that alone is faith.
We should know that he can bring good out of evil tragedy and pain, whatever situation we're in, he will help us through.

In most cases we don't deserve his help because of little faith we have in him that is always accompanied by doubt.
It is our faith that can help us..Ephesians 2:8 "for by grace you have been saved through faith".
