level of faith

I have a thing about waiting for buses and praying for them. So, just wanna share one of them:

That day, I was leaving from work and since I was late, I prayed for my bus to come. As soon as I did that, I started to hurry to the bus stop, for I knew in my heart that God was gonna send the bus to me. And the moment I set foot on the bus stop, my bus arrived! At that point, there was only one thing on my mind,

"If you have the faith to believe, God will be faithful to deliver."
..just a revelation to a very simple example.

when you believe, believe with all your heart, mind and body.
