why so surprised?

so let me get this,  the God of the universe, the One who created everything i see, feel, touch and smell, promises me in His word, over and over again, that He will provide for me. so why am i surprised when He does what He says He will do???  i mean, we are talking about the God who formed me in my mother's womb. He hung the stars in space. He created everything i set my eyes on. He is responsible for every single breath i take. He brings the sun up morning after morning. yet, every time i need something, and He comes thru and provides for me, why am i astonished? why am i surprised when He takes care of me? i am His child. i wouldn't let Ava go without something that she needs. and i don't love her even a fraction of the amount God loves me! God, forgive me for not having more faith.
