Today Jesus is reminding us that we should have unlimited faith and confidence in God. No prayer that we utter goes unheard. God is never out of his office; he's never on vacation.
He is longing for us to bombard him with our prayers. He is eagerly searching for hearts that trust him enough to ask him unceasingly for everything they need. He always answers our prayers, even when the answer is "no". Because God is our Father, all-wise, all-loving, and all-powerful, there should be no limit to our confidence in him.
