Jeremiah 33:2-3

Thus says the Lord who made the earth, the Lord who formed it to establish it-the Lord is His name. 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.  

With God, we always look at the tip of the iceberg regarding knowledge and relationship with Him. There is so much we don’t see waiting for us to learn and know about the things of God. When we call to Him, God will answer as we fellowship with the Lord in the Bible and prayer. God will bring to us knowledge, understanding, and revelation.
