Jeremiah 33:3

Call to Me and I will answer you, and tell you (and even show you) great and mighty things, (things which have been confined and hidden), which you do not know and understand and cannot distinguish.  

God responds to faith and will teach those who want to learn. When we cry out to God for understanding in confidence and not fear, God will reveal answers to us.   Like a child asks questions of a parent, we are to call to God, and God will show us mighty things.
