When God says No

Examine what motivates your prayers. Selfish motives yield selfish requests that are not answered.

You ask and do not receive because you ask wrongly, to spend it on your passions (James 4:3).

(Improper motives are not the only reason for unanswered prayer.)

Want what God wants

If want what God wants, you can ask and He will give it.

But, sometimes we ask and do not receive because we ask wrongly, to spend it on our passions (from James 4:3).
