He [God] expects us to trust Him and to be wise. This is the theme of Proverbs, especially chapter 2. Consider verses 1-6 (NIV):
My son, if you accept my words and store up my commands within you, turning your ear to wisdom and applying your heart to understanding, and if you call out for insight and cry aloud for understanding, and if you look for it as for silver and search for it as for hidden treasure, then you will understand the fear of the Lord and find the knowledge of God. For the Lord gives wisdom, and from his mouth come knowledge and understanding.
