I Samuel 8:21 And Samuel heard all the words of the people, and he rehearsed them in the ears of the LORD.
Samuel knew, obviously, that God already knew what was going on . He still went to God in prayer and told Him all about what was happening. He rehearsed them in the ears of the Lord. He spent time talking over with God what was going on even though God, as all knowing, omniscient, already knew.
That is a picture of our relationship with God. He knows. We know He knows. We still love Him. We run to Him. We tell Him about all of our troubles. He hears us. He answers us. God is much more interrelated and acting towards us than many would have you to believe.
Go to Him in prayer. Tell Him all of it. Expect Him to listen and respond.
