Knowing God by: Praying to Him

 "But whenever they were in trouble and turned to the Lord, the God of Israel, and sought Him out, they found Him."
2 Chronicles 15:4

You've probably played Hide and Seek before. The goal of the game is to hide really good, so the person who is "It" can not find you.
So you look for the best hiding place hoping you become invisible. 
It's a fun game to play, but it's not one you can play with God. When you look for Him, you will find out that he is actually not hiding. It's more like He's jumping in front of you waving His hands in the air because he wants to be found.
He wants you to know that He will always be there and you can ask Him ANYTHING.
You can ask Him anything by praying to Him.
